[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0020] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "thickness", "width", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. The term "connection" in this application mainly refers to a physical structural connection unless otherwise specified. In the case of specific explanations, it may also include meanings such as electrical connection, direct connection, or indirect connection. The term "coupling" in this application generally includes methods such as electrical connection, direct connection, or indirect connection. In the description of the embodiments of the present invention, terms such as "first" and "second" are not specific designations, but are used to distinguish objects with the same name. In the case where the specification clearly states, the objects with the same name referred to by terms such as "first" and "second" may be the same object. Among them, in this application, "A" and / or "B" includes three relationships: only "A", only "B", and both "A" and "B" included at the same time. In this application, "A" / "B" means "A" or "B".

[0021] Please refer to Figure 1 , which is a simple structural schematic diagram of the radio frequency module 1 in some embodiments of this application. As Figure 1 shown, the radio frequency module 1 includes a radio frequency transceiver 11 and a radio frequency processing module 12. The radio frequency processing module 12 is connected between the radio frequency transceiver 11 and the corresponding antenna 2 and is used to at least realize the transceiver processing of electromagnetic wave signals in the first frequency band, the second frequency band, and the third frequency band. Among them, the first frequency band and the second frequency band are time-division mode frequency bands, and the third frequency band is a frequency-division mode frequency band. Among them, under the transceiver processing of the radio frequency processing module 12, the radio frequency module 1 periodically and at least alternately performs the transceiver of electromagnetic wave signals in the first frequency band and the second frequency band. Each cycle at least includes a first stage and a second stage. In the first stage, the electromagnetic wave signal in the first frequency band is transmitted and the electromagnetic wave signal in the second frequency band is received. In the second stage, the electromagnetic wave signal in the first frequency band is received and the electromagnetic wave signal in the second frequency band is transmitted. And in the first stage and the second stage of each cycle, the radio frequency module 1 simultaneously transmits and receives electromagnetic wave signals in the third frequency band.

[0022] Thus, in the present application, by periodically and at least alternately transmitting and receiving electromagnetic wave signals of a first frequency band and electromagnetic wave signals of a second frequency band in the radio frequency module 1, and each period includes at least a first stage and a second stage. In the first stage, the radio frequency module 1 transmits electromagnetic wave signals of the first frequency band and receives electromagnetic wave signals of the second frequency band. In the second stage, the radio frequency module 1 receives electromagnetic wave signals of the first frequency band and transmits electromagnetic wave signals of the second frequency band. And in the first stage and the second stage of each period, the radio frequency module 1 simultaneously transmits and receives electromagnetic wave signals of a third frequency band. Thus, within one period, three-way uplink transmission can be achieved, and the uplink communication quality can be effectively improved.

[0023] Among them, the time-division mode frequency band means that the uplink frequency band (transmission frequency band) and the downlink frequency band (reception frequency band) of the electromagnetic wave signals of the frequency band are the same, and the uplink and downlink are alternately performed, that is, the transmission and reception of the electromagnetic wave signals of the frequency band are alternately realized in a time-division manner. Among them, the frequency-division mode frequency band means that the uplink frequency band (transmission frequency band) and the downlink frequency band (reception frequency band) of the electromagnetic wave signals of the frequency band are different. Thus, transmission and reception are simultaneously realized in a frequency-division manner.

[0024] Among them, in some embodiments, the period can be a transceiver period, which can be approximately equal to the period of one transceiver of the time-division mode frequency band. Since the period is usually short, for example, in milliseconds, the transmission within the period can be regarded as simultaneous transmission. Therefore, in the present application, the electromagnetic wave signals of the first frequency band are transmitted in the first stage within the period, the electromagnetic wave signals of the second frequency band are transmitted in the second stage within the period, and the electromagnetic wave signals of the third frequency band are transmitted in the first stage and the second stage of each period. Therefore, it is equivalent to being able to simultaneously achieve three-way transmission, that is, three-way uplink transmission, and the uplink communication quality can be effectively improved.

[0025] Among them, in the present application, when the radio frequency processing module 12 at least realizes the transceiver processing of electromagnetic wave signals of the first frequency band, the second frequency band, and the third frequency band, the antennas 2 connected to the radio frequency processing module 12 can be the same or at least partially different. For example, different antennas 2 can be used to support the transceiver of electromagnetic wave signals of the first frequency band, the second frequency band, and the third frequency band respectively, or the same antenna 2 can be used to support the transceiver of electromagnetic wave signals of the first frequency band, the second frequency band, and the third frequency band simultaneously. This will be described in more specific embodiments later. Figure 1 In [the figure], an example where the radio frequency processing module 12 is connected to the same antenna 2 is schematically shown.

[0026] Please refer to Figure 2 , which is another schematic diagram of a simple structure of the radio frequency module 1 in some embodiments of the present application.

[0027] In some embodiments, such as Figure 2 shown, the radio frequency processing module 12 includes a first transceiver processing circuit 13 and a second transceiver processing circuit 14. The first transceiver processing circuit 13 is connected between the radio frequency transceiver 11 and the corresponding antenna 2, and is used to at least implement the transceiver processing of electromagnetic wave signals in a first frequency band and a second frequency band. The second transceiver processing circuit 14 is connected between the radio frequency transceiver 11 and the corresponding antenna 2, and is used to at least implement the transceiver processing of electromagnetic wave signals in a third frequency band. Wherein, the first transceiver processing circuit 13 is in a first connection state in a first stage of each cycle, and is in a second connection state in a second stage of each cycle, and at least periodically alternates between the first connection state and the second connection state. In the first connection state, the first transceiver processing circuit 13 at least cooperates to form a transmission channel for the first frequency band and a reception channel for the second frequency band, so as to implement the transmission of electromagnetic wave signals in the first frequency band and the reception of electromagnetic wave signals in the second frequency band. In the second connection state, the first transceiver processing circuit 13 at least cooperates to form the reception channel for the first frequency band and the transmission channel for the second frequency band, so as to implement the reception of electromagnetic wave signals in the first frequency band and the transmission of electromagnetic wave signals in the second frequency band. Wherein, the second transceiver processing circuit 14 at least cooperates to form the transmission channel and the reception channel for the third frequency band in both the first stage and the second stage of each cycle, and simultaneously implements the reception and transmission of electromagnetic wave signals in the third frequency band.

[0028] That is, in some embodiments, the radio frequency processing module 12 includes two transceiver processing circuits, namely the first transceiver processing circuit 13 and the second transceiver processing circuit 14. By the first transceiver processing circuit 13 being in the first connection state in the first stage of each cycle to at least cooperate to form a transmission channel for the first frequency band and a reception channel for the second frequency band, and being in the second connection state in the second stage of each cycle to at least cooperate to form the reception channel for the first frequency band and the transmission channel for the second frequency band, so as to implement the transmission of electromagnetic wave signals in the first frequency band and the reception of electromagnetic wave signals in the second frequency band in the first stage of each cycle, and the reception of electromagnetic wave signals in the first frequency band and the transmission of electromagnetic wave signals in the second frequency band in the second stage of each cycle. In addition, by the second transceiver processing circuit 14 at least cooperating to form the transmission channel and the reception channel for the third frequency band in both the first stage and the second stage of each cycle, and simultaneously implementing the reception and transmission of electromagnetic wave signals in the third frequency band.

[0029] Among them, the first transceiver processing circuit 13 at least cooperates to form a transmission channel for the first frequency band and a reception channel for the second frequency band. This may include the case where the first transceiver processing circuit 13 cooperates with other devices to form a transmission channel for the first frequency band and a reception channel for the second frequency band, or the case where the first transceiver processing circuit 13 independently forms a transmission channel for the first frequency band and a reception channel for the second frequency band. The first transceiver processing circuit 13 at least cooperates to form the reception channel for the first frequency band and the transmission channel for the second frequency band. This may also include the case where the first transceiver processing circuit 13 cooperates with other devices to form the reception channel for the first frequency band and the transmission channel for the second frequency band, and may further include the case where the first transceiver processing circuit 13 independently forms the reception channel for the first frequency band and the transmission channel for the second frequency band.

[0030] Please refer to Figure 3 , which is a further structural schematic diagram of the radio frequency module 1 in some embodiments of this application.

[0031] As Figure 3 shown, the first transceiver processing circuit 13 includes a first power amplification unit 131. The transmission channel T11 for the first frequency band and the transmission channel T12 for the second frequency band share the first power amplification unit 131. Among them, the first power amplification unit 131 is used to amplify the electromagnetic wave signal / radio frequency signal for the first frequency band or the electromagnetic wave signal / radio frequency signal for the second frequency band output by the radio frequency transceiver 11.

[0032] That is, in some embodiments, the transmission channel T11 for the first frequency band and the transmission channel T12 for the second frequency band can share the first power amplification unit 131 to amplify the signal. Thus, since the transmission channels of the two frequency bands share the first power amplification unit 131, the number of power amplification devices can be effectively reduced, the structure of the radio frequency module can be simplified, and costs can be saved.

[0033] In some embodiments, the first frequency band and the second frequency band are within the same preset frequency range.

[0034] That is, in some embodiments, the first frequency band and the second frequency band are within the same preset frequency range. Thus, the frequency ranges or center frequencies corresponding to the first frequency band and the second frequency band are relatively close, and the first power amplification unit 131 can be shared to amplify the signal.

[0035] In some embodiments, the preset frequency range includes any one of a low-frequency range, an intermediate-frequency range, a high-frequency range, and an ultra-high-frequency range.

[0036] That is, in some embodiments, both the first frequency band and the second frequency band may be frequency bands in the low-frequency frequency range, or both in the medium-frequency frequency range, or both in the high-frequency frequency range, or both in the ultra-high-frequency frequency range.

[0037] Among them, the low-frequency frequency range may be a frequency range below 1 GHz, the medium-frequency frequency range may be a frequency range from 1 GHz to 2 GHz, the high-frequency frequency range may be a frequency range from 2 GHz to 3 GHz, and the ultra-high-frequency frequency range may be a frequency range above 3 GHz.

[0038] In some embodiments, the first power amplification unit 131 may correspondingly be any one of a low-frequency power amplification unit, a medium-frequency power amplification unit, a high-frequency power amplification unit, and an ultra-high-frequency power amplification unit, and can amplify the electromagnetic wave signal / radio frequency signal of the first frequency band and the electromagnetic wave signal / radio frequency signal of the second frequency band output by the radio frequency transceiver 11.

[0039] In some embodiments, the first frequency band and the second frequency band may be time-division mode frequency bands in the high-frequency frequency range. For example, the first frequency band may be the N41 frequency band, and the second frequency band may be the N40 frequency band. In some embodiments, the third frequency band may be a frequency-division mode frequency band in the high-frequency frequency range, for example, it may be the N7 frequency band.

[0040] Obviously, the first frequency band and the second frequency band may be any two suitable time-division mode frequency bands in the preset frequency range, and the third frequency band may also be any other frequency-division mode frequency band.

[0041] In other embodiments, the preset frequency range may also refer to any range covering a preset frequency bandwidth, such as a range covering a frequency bandwidth of 600 MHz or 700 MHz, etc., without necessarily being the low-frequency frequency range, the medium-frequency frequency range, or the high-frequency frequency range, etc. When the first frequency band and the second frequency band are within the frequency bandwidth range, the center frequencies of the first frequency band and the second frequency band are relatively close, and the first power amplification unit 131 can be shared to amplify the signals.

[0042] In some embodiments, as Figure 3 shown, the first power amplification unit 131 may at least include a first power amplifier A1, and the first power amplifier A1 amplifies the electromagnetic wave signal / radio frequency signal of the first frequency band or the electromagnetic wave signal / radio frequency signal of the second frequency band output by the radio frequency transceiver 11. In some embodiments, devices such as filters may also be integrated in the first power amplification unit 131.

[0043] In some embodiments, the first transceiver processing circuit 13 further includes a first low-noise amplifier (LNA) 132 and a second low-noise amplifier 133. The first low-noise amplifier 132 is located in the receiving channel T13 of the first frequency band, and the second low-noise amplifier 133 is located in the receiving channel T14 of the second frequency band.

[0044] Among them, the first low-noise amplifier 132 is configured to amplify the electromagnetic wave signal of the first frequency band received by the corresponding antenna 2 and then transmit it to the radio frequency transceiver 11 to realize the reception of the electromagnetic wave signal of the first frequency band. The second low-noise amplifier 133 is configured to amplify the electromagnetic wave signal of the second frequency band received by the corresponding antenna 2 and then transmit it to the radio frequency transceiver 11 to realize the reception of the electromagnetic wave signal of the second frequency band.

[0045] As Figure 3 shown, in some embodiments, the first transceiver processing circuit 13 further includes a first transmit filter 134, a second transmit filter 135, and a transmit selection switch 136. The first transmit filter 134 is configured to filter the electromagnetic wave signal of the first frequency band, and the second transmit filter 135 is configured to filter the electromagnetic wave signal of the second frequency band, thereby effectively filtering out noise. Among them, the transmit selection switch 136 is connected between the first transmit filter 134, the second transmit filter 135, and the first power amplification unit 131. The transmit selection switch 136 is configured to select and establish a connection between the first power amplification unit 131 and the first transmit filter 134 in the first connection state, and select and establish a connection between the first power amplification unit 131 and the second transmit filter 135 in the second connection state.

[0046] Among them, as Figure 3As shown, the first power amplifier unit 131 is connected between the RF transceiver 11 and the transmit selection switch 136, and both the first transmit filter 134 and the second transmit filter 135 are coupled to the corresponding antenna 2. Among them, in the first connection state, the transmit selection switch 136 establishes a connection between the first power amplifier unit 131 and the first transmit filter 134. Thus, the electromagnetic wave signal in the first frequency band output by the RF transceiver 11 can be amplified by the first power amplifier unit 131, then filtered by the first transmit filter 134, and then output to the corresponding antenna 2 and transmitted through the corresponding antenna 2, so as to realize the transmission of the electromagnetic wave signal in the first frequency band. In the second connection state, the transmit selection switch 136 establishes a connection between the first power amplifier unit 131 and the second transmit filter 135. Thus, the electromagnetic wave signal in the second frequency band output by the RF transceiver 11 can be amplified by the first power amplifier unit 131, then filtered by the second transmit filter 135, and then output to the corresponding antenna 2 and transmitted through the corresponding antenna 2, so as to realize the transmission of the electromagnetic wave signal in the second frequency band.

[0047] Among them, the first transmit filter 134 and the second transmit filter 135 can be band-pass filters. The first transmit filter 134 can only allow the electromagnetic wave signal in the first frequency band to pass through, while filtering out the electromagnetic wave signals in other frequency bands outside the first frequency band. Thus, the noise outside the first frequency band is filtered out. The second transmit filter 135 can only allow the electromagnetic wave signal in the second frequency band to pass through, while filtering out the electromagnetic wave signals in other frequency bands outside the second frequency band. Thus, the noise outside the second frequency band is filtered out.

[0048] Among them, in some embodiments, the RF transceiver 11 outputs an electromagnetic wave signal in the first frequency band to the first power amplifier unit 131 in the first stage of each cycle, and outputs an electromagnetic wave signal in the second frequency band to the first power amplifier unit 131 in the second stage of each cycle.

[0049] In some embodiments, the RF transceiver 11 can also output electromagnetic wave signals of the first frequency band and the second frequency band simultaneously in each cycle. In the first connection state, when the transmission selection switch 136 establishes a connection between the first power amplification unit 131 and the first transmission filter 134, since the first transmission filter 134 only allows electromagnetic wave signals of the first frequency band to pass through, only the electromagnetic wave signals of the first frequency band are output to the corresponding antenna 2 and transmitted through the corresponding antenna 2. In the second connection state, when the transmission selection switch 136 establishes a connection between the first power amplification unit 131 and the second transmission filter 135, since the second transmission filter 135 only allows electromagnetic wave signals of the second frequency band to pass through, only the electromagnetic wave signals of the second frequency band are output to the corresponding antenna 2 and transmitted through the corresponding antenna 2.

[0050] Therefore, the signals output by the RF transceiver 11 to the first power amplification unit 131 can be electromagnetic wave signals of the first frequency band and / or the second frequency band.

[0051] In some embodiments, as Figure 3 shown, the RF transceiver 11 includes a first signal transmission end Tx1. The first power amplification unit 131 is specifically connected between the first signal transmission end Tx1 of the RF transceiver 11 and the transmission selection switch 136. The RF transceiver 11 outputs electromagnetic wave signals of the first frequency band and / or the second frequency band to the first power amplification unit 131 through the first signal transmission end Tx1.

[0052] Among them, in some embodiments, the transmission selection switch 136 can be a single-pole double-throw switch, including a fixed end and two free ends. The fixed end of the transmission selection switch 136 is connected to the first power amplification unit 131. The two free ends of the transmission selection switch 136 are respectively connected to the first transmission filter 134 and the second transmission filter 135. The fixed end can be selectively connected to one of the free ends, so as to selectively establish a connection between the first power amplification unit 131 and the first transmission filter 134, or establish a connection between the first power amplification unit 131 and the second transmission filter 135.

[0053] In some embodiments, as Figure 3As shown, the first transceiver processing circuit 13 further includes a channel selection switch 137, and the channel selection switch 137 is connected between the first low-noise amplifier 132, the second low-noise amplifier 133, the first transmit filter 134, the second transmit filter 135, and the corresponding antenna 2; in the first connection state, the transmit selection switch 136 establishes a connection between the first power amplifier unit 131 and the first transmit filter 134, and the channel selection switch 137 establishes a connection between the first transmit filter 134 and the corresponding antenna 2, and establishes a connection between the second low-noise amplifier 133 and the corresponding antenna 2, so that the first transceiver processing circuit 13 forms a transmit channel for the first frequency band and a receive channel for the second frequency band. In the second connection state, the transmit selection switch 136 establishes a connection between the first power amplifier unit 131 and the second transmit filter 135, and the channel selection switch 137 establishes a connection between the second transmit filter 135 and the corresponding antenna 2, and establishes a connection between the first low-noise amplifier 132 and the corresponding antenna 2, so that the first transceiver processing circuit 13 forms a receive channel for the first frequency band and a transmit channel for the second frequency band.

[0054] That is, in some embodiments, the first transceiver processing circuit 13 further includes a channel selection switch 137, and the channel selection switch 137 is connected between the first low-noise amplifier 132, the second low-noise amplifier 133, the first transmit filter 134, the second transmit filter 135, and the corresponding antenna 2. By cooperating the channel selection switch 137 with the transmit selection switch 136, a transmit channel T11 for the first frequency band and a receive channel T14 for the second frequency band can be formed in the first connection state, and a receive channel T13 for the first frequency band and a transmit channel T12 for the second frequency band can be formed in the second connection state.

[0055] Therefore, in some embodiments, when the first transceiver processing circuit 13 further includes a channel selection switch 137, the first transceiver processing circuit 13 can independently form a receive channel for the first frequency band and a transmit channel for the second frequency band at this time.

[0056] In some embodiments, the channel selection switch 137 can be a multiplexer and can establish one or at least two connections simultaneously. Thus, in the first connection state, a connection between the first transmit filter 134 and the corresponding antenna 2 can be established, and a connection between the second low-noise amplifier 133 and the corresponding antenna 2 can be established, and in the second connection state, a connection between the second transmit filter 135 and the corresponding antenna 2 can be established, and a connection between the first low-noise amplifier 132 and the corresponding antenna 2 can be established.

[0057] In some embodiments, such asFigure 3 As shown, the radio frequency transceiver 11 further includes a first signal receiving end Rx1 and a second signal receiving end Rx2. In some embodiments, the first low-noise amplifier 132 may be specifically connected between the first signal receiving end Rx1 and the channel selection switch 137, and the second low-noise amplifier 133 may be specifically connected between the second signal receiving end Rx2 and the channel selection switch 137.

[0058] Among them, as Figure 3 shown, in some embodiments, when the first transceiver processing circuit 13 is in the first connection state to form the transmission channel T11 of the first frequency band and the reception channel T14 of the second frequency band, the transmission channel T11 of the first frequency band may specifically include the channel portion between the first signal end Tx1 of the radio frequency transceiver 11 where the first power amplification unit 131 is located and the transmission selection switch 136, the channel portion between the transmission selection switch 136 where the first transmission filter 134 is located and the channel selection switch 137, and the channel portion between the channel selection switch 137 and the corresponding antenna 2. The reception channel T14 of the second frequency band may include the channel portion between the second signal receiving end Rx2 where the second low-noise amplifier 133 is located and the channel selection switch 137, and the channel portion between the channel selection switch 137 and the corresponding antenna 2. Among them, when the first transceiver processing circuit 13 is in the second connection state to form the reception channel T13 of the first frequency band and the transmission channel T12 of the second frequency band, the transmission channel T12 of the second frequency band may specifically include the channel portion between the first signal end Tx1 of the radio frequency transceiver 11 where the first power amplification unit 131 is located and the transmission selection switch 136, the channel portion between the transmission selection switch 136 where the second transmission filter 135 is located and the channel selection switch 137, and the channel portion between the channel selection switch 137 and the corresponding antenna 2. The reception channel T13 of the first frequency band may include the channel portion between the first signal receiving end Rx1 where the first low-noise amplifier 132 is located and the channel selection switch 137, and the channel portion between the channel selection switch 137 and the corresponding antenna 2.

[0059] Among them, as Figure 3As shown, the first transceiver processing circuit 13 further includes a first receive filter 138 and a second receive filter 139. Among them, the first receive filter 138 is located in the receive channel T13 of the first frequency band and is used to filter the electromagnetic wave signal of the first frequency band received by the corresponding antenna 2. The second receive filter 139 is located in the receive channel T14 of the second frequency band and is used to filter the electromagnetic wave signal of the second frequency band received by the corresponding antenna 2. Among them, as Figure 3 shown, in some embodiments, the first receive filter 138 may be located between the first low-noise amplifier 132 and the channel selection switch 137. The first receive filter 138 may first filter the electromagnetic wave signal of the first frequency band and then transmit the filtered electromagnetic wave signal of the first frequency band to the first low-noise amplifier 132 for amplification, and then input it to the first signal receiving end Rx1 of the radio frequency transceiver 11 to achieve the reception of the electromagnetic wave signal of the first frequency band. As Figure 3 shown, in some embodiments, the second receive filter 139 may be located between the second low-noise amplifier 133 and the channel selection switch 137. Thus, the second receive filter 139 may first filter the electromagnetic wave signal of the first frequency band and then transmit the filtered electromagnetic wave signal of the second frequency band to the second low-noise amplifier 133 for amplification, and then input it to the second signal receiving end Rx2 of the radio frequency transceiver 11 to achieve the reception of the electromagnetic wave signal of the second frequency band.

[0060] As Figure 3 shown, in some embodiments, the second transceiver processing circuit 14 includes a second power amplification unit 141, a third low-noise amplifier 142, and a duplexer 143. The duplexer 143 is coupled between the second power amplification unit 141, the third low-noise amplifier 142, and the corresponding antenna 2. The second power amplification unit is connected between the radio frequency transceiver 11 and the duplexer 143. The third low-noise amplifier 142 is also connected between the radio frequency transceiver 11 and the duplexer 143.

[0061] Among them, in some embodiments, the duplexer 143 may include a transmit filter 143a and a receive filter 143b. The duplexer 143 performs transmit filtering and receive filtering of the electromagnetic wave signal of the third frequency band through the internal transmit filter 143a and receive filter 143b.

[0062] Among them, the transmitting filter 143a and the receiving filter 143b may both be band-pass filters. The transmitting filter 143a is used to only allow the electromagnetic wave signals in the uplink frequency band of the third frequency band to pass through, so as to filter the electromagnetic wave signals outside the uplink frequency band of the third frequency band. The receiving filter 143b is used to only allow the electromagnetic wave signals in the downlink frequency band of the third frequency band to pass through, so as to filter the electromagnetic wave signals outside the downlink frequency band of the third frequency band.

[0063] Among them, as Figure 3 shown, the second transceiver processing circuit 14 includes a second signal transmitting end Tx2 and a third signal receiving end Rx3. The second power amplification unit 141 is specifically connected between the second signal transmitting end Tx2 of the radio frequency transceiver 11 and the transmitting filter 143a inside the duplexer 143. The third low-noise amplifier 142 is specifically connected between the third signal receiving end Rx3 of the radio frequency transceiver 11 and the receiving filter 143b inside the duplexer 143.

[0064] Among them, the transmitting channel T21 of the third frequency band formed by the second transceiver processing circuit 14 includes a channel part between the second signal transmitting end Tx2 and the duplexer 143 and a channel part between the duplexer 143 and the corresponding antenna 2. The receiving channel T22 of the third frequency band formed by the second transceiver processing circuit 14 includes a channel part between the third signal receiving end Rx3 and the duplexer 143 and a channel part between the duplexer 143 and the corresponding antenna 2.

[0065] Among them, the second power amplification unit 141 may at least include a second power amplifier A2. The second power amplifier is used to amplify the electromagnetic wave signals of the third frequency band output by the radio frequency transceiver 11, and then output them to the transmitting filter 143a of the duplexer 143. After being filtered by the transmitting filter 143a, they are transmitted to the corresponding antenna 2 for transmission. Among them, the electromagnetic wave signals of the third frequency band received by the corresponding antenna 2 are filtered by the receiving filter 143b inside the duplexer 143, then amplified by the third low-noise amplifier 142, and input to the radio frequency transceiver 11 through the third signal receiving end Rx3.

[0066] In some embodiments, the second power amplification unit 141 may further include devices such as filters.

[0067] In some embodiments, as Figure 3As shown, the second transceiver processing circuit 14 further includes a path switch 144. The path switch 144 is connected between the duplexer 143 and the corresponding antenna 2, and is used to establish a connection between the duplexer 143 and the corresponding antenna 2 in both the first stage and the second stage of each cycle.

[0068] Thus, in some embodiments, the second transceiver processing circuit 14 can also independently form the transmit channel T21 and the receive channel T22 of the third frequency band.

[0069] Wherein, the path switch 144 can be a single-pole single-throw switch. The terminals of the transmit filter 143a and the receive filter 143b of the duplexer 143 for connecting to the antenna 2 can be connected together, and then connected to one end of the path switch 144. The other end of the path switch 144 is connected to the corresponding antenna 2.

[0070] Please refer to Figure 4 FIG. for a further schematic structural diagram of the radio frequency module 1 in some embodiments of the present application.

[0071] As Figure 4 shown, in some embodiments, the first transceiver processing circuit 13 may not include the channel selection switch 137. The radio frequency processing module 12 further includes an array switch 15. The array switch 15 is connected between the first low-noise amplifier 132, the second low-noise amplifier 133, the first transmit filter 134, the second transmit filter 135, and the corresponding antenna 2. In the first connection state, the transmit selection switch 136 establishes a connection between the first power amplification unit 131 and the first transmit filter 134, and the array switch 15 establishes a connection between the first transmit filter 134 and the corresponding antenna 2, and establishes a connection between the second low-noise amplifier 133 and the corresponding antenna 2, thereby forming the transmit channel T11 of the first frequency band and the receive channel T14 of the second frequency band. In the second connection state, the transmit selection switch 136 establishes a connection between the first power amplification unit 131 and the second transmit filter 135, and the array switch 15 establishes a connection between the second transmit filter 135 and the corresponding antenna 2, and establishes a connection between the first low-noise amplifier 132 and the corresponding antenna 2, thereby forming the receive channel T13 of the first frequency band and the transmit channel T12 of the second frequency band.

[0072] Thus, in some embodiments, the first transceiver processing circuit 13 can cooperate with the array switch 15 to form the transmit channel T11 of the first frequency band and the receive channel T14 of the second frequency band in the first connection state, and form the receive channel T13 of the first frequency band and the transmit channel T12 of the second frequency band in the second connection state.

[0073] In some embodiments, when the radio frequency processing module 12 further includes the array switch 15, the second transceiver processing circuit 14 may not include the path switch 144 either. Wherein, as Figure 3 shown, the array switch 15 is also connected between the duplexer 143 of the second transceiver processing circuit 14 and the corresponding antenna 2, and is used to establish a connection between the duplexer 143 and the corresponding antenna 2 in both the first stage and the second stage of each cycle.

[0074] Thus, in some embodiments, the second transceiver processing circuit 14 can cooperate with the array switch 15 to form the transmission channel T21 of the third frequency band and the reception channel T22 of the third frequency band in both the first connection state and the second connection state.

[0075] Wherein, Figure 4 and Figure 3 The main difference is that the first transceiver processing circuit 13 may not include the channel selection switch 137, and the second transceiver processing circuit 14 may not include the path switch 144 either. The radio frequency processing module 12 further includes an array switch 15, and the array switch 15 can replace the channel selection switch 137 and the path switch 144. Wherein, in some embodiments, Figure 3 the shown channel selection switch 137 and the path switch 144 can be regarded as integrated in the array switch 15.

[0076] Wherein, Figure 4 other structures in Figure 3 are the same as those in Figure 3 For more specific content, reference can be made to the relevant description in

[0077] Wherein, the array switch 15 can be a multi-way switch array and can establish multiple connections simultaneously.

[0078] Wherein, the following takes the structure shown in Figure 4 as an example to give an overall introduction to the process in one transceiver cycle of the radio frequency module 1 for transmitting and receiving electromagnetic waves of the first frequency band, the second frequency band, and the third frequency band.

[0079] Wherein, in some embodiments, when the radio frequency module 1 periodically alternates at least between transmitting and receiving electromagnetic wave signals of the first frequency band and electromagnetic wave signals of the second frequency band, each cycle may only include a first stage and a second stage. At this time, the first stage can also be called the first half cycle, and the second stage can also be called the second half cycle.

[0080] Among them, the transmission process in the first stage includes: the first signal transmitting end Tx1 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the first frequency band. After being amplified by the first power amplification unit 131, it is transmitted to the first transmission filter 134 connected through the transmission selection switch 136 for filtering, and then transmitted to the corresponding connected antenna 2 for transmission through the array switch 15. At the same time, the second signal transmitting end Tx2 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the third frequency band. After being amplified by the second power amplification unit 141 and filtered by the duplexer 143, it is transmitted to the corresponding connected antenna 2 for transmission through the array switch 15.

[0081] The receiving process in the first stage includes: the electromagnetic wave signal in the second frequency band received by the corresponding antenna 2 is transmitted to the second receiving filter 139 through the array switch 15. After being filtered by the first receiving filter 138 for the electromagnetic wave signal in the second frequency band, it is transmitted to the second low-noise amplifier 133 for amplification, and then input to the second signal receiving end Rx2 of the radio frequency transceiver 11. At the same time, the electromagnetic wave signal in the third frequency band received by the corresponding antenna 2 is transmitted to the duplexer 143 through the array switch 15. After being filtered by the duplexer 143, it is transmitted to the third low-noise amplifier 142, and after being amplified by the third low-noise amplifier 142, it is input to the third signal receiving end Rx3 of the radio frequency transceiver 11.

[0082] Among them, the transmission process and the receiving process in the first stage are carried out simultaneously. Thus, as described above, the transmission of the electromagnetic wave signal in the first frequency band and the reception of the electromagnetic wave signal in the second frequency band are realized simultaneously, and the transmission and reception of the electromagnetic wave signal in the third frequency band are also carried out simultaneously.

[0083] Among them, the transmission process in the second stage includes: the first signal transmitting end Tx1 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the second frequency band. After being amplified by the first power amplification unit 131, it is transmitted to the second transmission filter 135 connected through the transmission selection switch 136 for filtering, and then transmitted to the corresponding connected antenna 2 for transmission through the array switch 15. At the same time, the second signal transmitting end Tx2 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the third frequency band. After being amplified by the second power amplification unit 141 and filtered by the duplexer 143, it is transmitted to the corresponding connected antenna 2 for transmission through the array switch 15.

[0084] The receiving process in the second stage includes: the electromagnetic wave signal in the first frequency band received by the corresponding antenna 2 is transmitted to the first receiving filter 138 through the array switch 15. After the first receiving filter 138 filters the electromagnetic wave signal in the first frequency band, it is then transmitted to the first low-noise amplifier 132 for amplification, and then input to the first signal receiving end Rx1 of the radio frequency transceiver 11; meanwhile, the electromagnetic wave signal in the third frequency band received by the corresponding antenna 2 is transmitted to the duplexer 143 through the array switch 15. After being filtered by the duplexer 143, it is transmitted to the third low-noise amplifier 142, and after being amplified by the third low-noise amplifier 142, it is input to the third signal receiving end Rx3 of the radio frequency transceiver 11.

[0085] Wherein, the transmitting process and the receiving process in the second stage are carried out simultaneously. Thus, as described above, the reception of the electromagnetic wave signal in the first frequency band and the transmission of the electromagnetic wave signal in the second frequency band are simultaneously realized, and the transmission and reception of the electromagnetic wave signal in the third frequency band are also carried out simultaneously.

[0086] Thus, in the present application, by staggering the transmission time slots of the time division mode frequency bands, multi-channel transmission can be realized within one cycle, effectively improving the uplink communication quality.

[0087] Wherein, in the present application, the radio frequency processing module 12 mainly realizes the transceiver processing of the electromagnetic wave signals in at least two time division mode frequency bands, namely the first frequency band and the second frequency band, and the frequency division mode frequency band, namely the third frequency band, and it is described that each cycle includes a first stage and a second stage.

[0088] In some embodiments, the radio frequency processing module 12 can also realize the transceiver processing of two or more time division mode frequency bands, and each cycle can also include two or more stages. For example, the radio frequency processing module 12 can also realize the transceiver processing of three time division mode frequency bands, and each cycle can also include a first stage, a second stage and a third stage in sequence. Each stage correspondingly forms a transmission channel for a time division mode frequency band. Thus, more channels of uplink communication can be realized, further improving the uplink communication quality.

[0089] In some embodiments, the frequency division mode frequency band can also include two or more, supporting more channels of uplink communication.

[0090] Please refer to Figure 5 , which is a further structural schematic diagram of the radio frequency module 1 in some embodiments of the present application.

[0091] In some embodiments, the RF processing module 12 further includes an auxiliary port P1, and the RF module 1 further includes an auxiliary filter 10. The auxiliary filter 10 is connected between the auxiliary port P1 and the corresponding antenna 2 for filtering the electromagnetic wave signals in the first frequency band. In some embodiments, as Figure 5 shown, the first transceiver processing circuit 13 further includes the aforementioned second transmit filter 135 and a transmit selection switch 136. The second transmit filter 135 is used for filtering the electromagnetic wave signals in the second frequency band. Among them, the transmit selection switch 136 is connected between the auxiliary port P1, the second transmit filter 135, and the first power amplification unit 131. The transmit selection switch 136 is configured to select and establish a connection between the first power amplification unit 131 and the auxiliary port P1 in the first connection state, and select and establish a connection between the first power amplification unit 131 and the second transmit filter 135 in the second connection state.

[0092] Among them, in some embodiments, Figure 5 compared with the foregoing Figure 3 or Figure 4 the main difference of the RF module 1 shown is that the first transmit filter 134 can be omitted, and the auxiliary port P1 and the auxiliary filter 10 are added. The auxiliary port P1 and the auxiliary filter 10 are used to replace Figure 3 and Figure 4 the first transmit filter 134 shown in

[0093] Among them, Figure 5 the RF processing module 12 including the array switch 15 is taken as an example for illustration. At this time, the array switch 15 is connected between the first low-noise amplifier 132, the second low-noise amplifier 133, the second transmit filter 135, and the corresponding antenna 2, and the auxiliary port P1 is directly connected to the corresponding antenna 2 through the auxiliary filter 10.

[0094] Among them, in the first connection state, the transmit selection switch 136 establishes a connection between the first power amplification unit 131 and the auxiliary port P1, and the array switch 15 establishes a connection between the first transmit filter 134 and the corresponding antenna 2, and establishes a connection between the second low-noise amplifier 133 and the corresponding antenna 2, so as to form a transmit channel T11 in the first frequency band and a receive channel T14 in the second frequency band. Among them, Figure 5Under the structure shown, the transmission channel T11 of the first frequency band can be the channel from the first signal transmission end Tx1 of the RF transceiver 11, passing through the first power amplification unit 131, through the transmission selection switch 136 to the auxiliary port P1, and through the auxiliary filter 10 to the corresponding antenna 2.

[0095] Among them, in the second connection state, the transmission selection switch 136 establishes the connection between the first power amplification unit 131 and the second transmission filter 135, the array switch 15 establishes the connection between the second transmission filter 135 and the corresponding antenna 2, and establishes the connection between the first low-noise amplifier 132 and the corresponding antenna 2, thereby forming the reception channel T13 of the first frequency band and the transmission channel T12 of the second frequency band.

[0096] In some embodiments, it can also be as Figure 3 shown, the first transceiver processing circuit 13 includes the channel selection switch 137. At this time, the channel selection switch 137 is connected between the first low-noise amplifier 132, the second low-noise amplifier 133, the second transmission filter 135, and the corresponding antenna 2, and establishes the connection between the first low-noise amplifier 132, the second low-noise amplifier 133, and / or the second transmission filter 135 and the corresponding antenna 2.

[0097] Among them, Figure 5 mainly shows other structures of the first transceiver processing circuit 13, and the structure of the second transceiver processing circuit 14 can be the same as the structure of the second transceiver processing circuit 14 in any of the foregoing embodiments.

[0098] Among them, as Figures 2 - 5 shown, since the first frequency band, the second frequency band, and the third frequency band are different from each other, therefore, the corresponding antenna 2 can be one, and by connecting the corresponding matching circuit, the antenna 2 can support resonance in the first frequency band, the second frequency band, and the third frequency band. In some embodiments, the corresponding antenna 2 can also be multiple, and the transceiver channels of different frequency bands can be connected to different antennas 2. Figures 2 - 5 In, an example with the corresponding antenna 2 being one is shown for illustration.

[0099] Please refer to Figure 6 , which is a further schematic structural diagram of the RF module 1 in some embodiments of the present application.

[0100] Among them, Figure 6 can be an additional structure added on the basis of the RF module 1 shown in the foregoing Figure 3 and Figure 4 .

[0101] AsFigure 6 As shown, in some embodiments, the RF processing module 12 further includes an auxiliary port P1, and the RF module 1 further includes an auxiliary filter 10. The auxiliary filter 10 is connected between the auxiliary port P1 and the corresponding antenna 2 for filtering the electromagnetic wave signals in the first frequency band. That is, in some embodiments, on the basis of the RF module 1 shown above Figure 3 or Figure 4 shown above, the auxiliary port P1 and the auxiliary filter 10 are further included.

[0102] Among them, as Figure 6 shown, the transmit selection switch 136 is further connected between the first power amplification unit 131 and the auxiliary port P1. The transmit selection switch 136 establishes the connection between the first power amplification unit 131 and the auxiliary port P1 as well as the first transmit filter 134 in the first connection state, and establishes the connection between the first power amplification unit 131 and the second transmit filter 135 in the second connection state.

[0103] That is, in some embodiments, the transmit selection switch 136 can be connected between the first transmit filter 134, the second transmit filter 135, the auxiliary port P1, and the first power amplification unit 131. And the transmit selection switch 136 establishes the connection between the first power amplification unit 131 and the auxiliary port P1 in the first connection state, and simultaneously establishes the connection between the first power amplification unit 131 and the first transmit filter 134, so as to realize the transmission of electromagnetic wave signals in two first frequency bands.

[0104] Among them, under the structure shown Figure 6 above, the transmit selection switch 136 can also be a multi-way selection switch, and multi-way simultaneous connection can be realized.

[0105] Among them, under the structure shown Figure 6 above, the corresponding antenna 2 includes at least two. That is, as Figure 6 shown, the corresponding antenna 2 includes at least antenna 21 and antenna 22. Among them, antenna 21 is connected to the auxiliary filter 10, and the other antennas 2, such as antenna 22, can be connected to the first transmit filter 134 and the second transmit filter through the array switch 15 or the channel selection switch 137, and connected to the duplexer 143 through the array switch 15 or the path switch 144.

[0106] Among them, under the structure shown Figure 6Under the shown structure, it is possible to implement at least a 2×2 MIMO (Multiple Input Multiple Output) antenna system in the first frequency band, which is beneficial to further improving the transmission performance and further enhancing the uplink communication quality.

[0107] Among them, Figure 6 in, taking the example of adding a further structure on the basis of the shown radio frequency module 1, that is, at this time, the radio frequency module 1 includes the array switch 15. Obviously, as described above, Figure 4 It is also possible to add a further structure on the basis of the shown radio frequency module 1, that is, at this time, the array switch 15 of the radio frequency module 1 can be replaced by the channel selection switch 137 and the path switch 144 respectively. Figure 6 Among them, Figure 3 the other structures in are the same as those in the foregoing

[0108] Among them, Figure 6 or Figure 3 shown structure, and for specific details, reference can be made to the relevant content in the foregoing Figure 4 or Figure 3 shown. Figure 4

[0109] Among them, taking the following Figure 6 shown structure as an example, the process in one transceiver cycle of the radio frequency module 1 for transceiver of electromagnetic waves in the first frequency band, the second frequency band, and the third frequency band will be introduced as a whole.

[0110] Among them, here it is also introduced by taking the example that each cycle may only include a first stage and a second stage. At this time, the first stage can also be called the first half cycle, and the second stage can also be called the second half cycle.

[0111] Among them, the transmission process in the first stage includes: the first signal transmission end Tx1 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the first frequency band, which is amplified by the first power amplification unit 131 and then transmitted to the auxiliary port P1 connected through the transmission selection switch 136, and after being filtered by the auxiliary filter 10, it is transmitted to the corresponding antenna 2 for transmission. At the same time, the electromagnetic wave signal in the first frequency band amplified by the first power amplification unit 131 is also transmitted through the transmission selection switch 136 to the first transmission filter 134 for filtering, and then transmitted through the array switch 15 to the correspondingly connected antenna 2 for transmission, thereby realizing the transmission of two paths of electromagnetic wave signals in the first frequency band; at the same time, the second signal transmission end Tx2 of the radio frequency transceiver 11 transmits an electromagnetic wave signal in the third frequency band, which is amplified by the second power amplification unit 141, filtered by the duplexer 143, and then transmitted through the array switch 15 to the correspondingly connected antenna 2 for transmission.

[0112] The receiving process in the first stage includes: the electromagnetic wave signal in the second frequency band received by the corresponding antenna 2 is transmitted to the second receiving filter 139 through the array switch 15. After the electromagnetic wave signal in the second frequency band is filtered by the first receiving filter 138, it is then transmitted to the second low-noise amplifier 133 for amplification and then input to the second signal receiving end Rx2 of the radio frequency transceiver 11. At the same time, the electromagnetic wave signal in the third frequency band received by the corresponding antenna 2 is transmitted to the duplexer 143 through the array switch 15, filtered by the duplexer 143 and then transmitted to the third low-noise amplifier 142, and after being amplified by the third low-noise amplifier 142, it is input to the third signal receiving end Rx3 of the radio frequency transceiver 11.

[0113] Among them, the transmitting process and the receiving process in the first stage are carried out simultaneously. Thus, as described above, the transmission of the electromagnetic wave signal in the first frequency band and the reception of the electromagnetic wave signal in the second frequency band are realized simultaneously, and the transmission and reception of the electromagnetic wave signal in the third frequency band are also carried out simultaneously.

[0114] Among them, the transmitting process in the second stage includes: the first signal transmitting end Tx1 of the radio frequency transceiver 11 transmits the electromagnetic wave signal in the second frequency band. After being amplified by the first power amplification unit 131, it is transmitted to the second transmitting filter 135 connected through the transmitting selection switch 136 for filtering, and then transmitted to the corresponding antenna 2 through the array switch 15 for transmission. At the same time, the second signal transmitting end Tx2 of the radio frequency transceiver 11 transmits the electromagnetic wave signal in the third frequency band. After being amplified by the second power amplification unit 141 and filtered by the duplexer 143, it is then transmitted to the corresponding antenna 2 through the array switch 15 for transmission.

[0115] The receiving process in the second stage includes: the electromagnetic wave signal in the first frequency band received by the corresponding antenna 2 is transmitted to the first receiving filter 138 through the array switch 15. After the electromagnetic wave signal in the first frequency band is filtered by the first receiving filter 138, it is then transmitted to the first low-noise amplifier 132 for amplification and then input to the first signal receiving end Rx1 of the radio frequency transceiver 11. At the same time, the electromagnetic wave signal in the third frequency band received by the corresponding antenna 2 is transmitted to the duplexer 143 through the array switch 15, filtered by the duplexer 143 and then transmitted to the third low-noise amplifier 142, and after being amplified by the third low-noise amplifier 142, it is input to the third signal receiving end Rx3 of the radio frequency transceiver 11.

[0116] Among them, the transmission process and the reception process in the second stage are carried out simultaneously. Thus, as described above, the reception of the electromagnetic wave signal in the first frequency band and the transmission of the electromagnetic wave signal in the second frequency band are realized simultaneously, and the transmission and reception of the electromagnetic wave signal in the third frequency band are also carried out simultaneously.

[0117] Thus, through the radio frequency module 1 of the present application, multi-path uplink communication can be realized simultaneously, and the uplink communication quality can be effectively improved.

[0118] Among them, as Figures 3 - 6 shown, the first low-noise amplifier 132, the second low-noise amplifier 133, and the third low-noise amplifier 142 are schematically shown as being located outside the radio frequency transceiver 11. In some embodiments, the first low-noise amplifier 132, the first low-noise amplifier 132, and the third low-noise amplifier 142 may also be integrated in the radio frequency transceiver 11.

[0119] In some embodiments, the radio frequency processing module 12 may be an integrated chip, that is, the devices included in the first transceiver processing circuit 13 and the second transceiver processing circuit 14 included in the radio frequency processing module 12 may all be integrated in the same chip.

[0120] Among them, the first transceiver processing circuit 13 and the second transceiver processing circuit 14 may physically include the foregoing structures, or may logically include the foregoing structures.
