Description

Technical Field

[0001] This application relates to the field of radio frequency technology, and more specifically, to a radio frequency transceiver system and a radio frequency receiver system. Background Technology

[0002] In wireless communication systems, the radio frequency front-end is a key component for signal transmission and reception, and is widely used in mobile terminal devices such as smartphones, IoT terminals, and communication modules.

[0003] Currently, Frequency Division Duplexing (FDD) is a duplexing method used in communications. It uses two independent but symmetrical frequency channels for uplink (transmit, TX) and downlink (receive, RX) communication, respectively. Traditional FDD typically uses a duplexer to isolate the transmit and receive signals. The duplexer integrates transmit and receive filters, which can separate the transmit and receive signals in terms of frequency at the same time, thereby avoiding mutual interference and sharing the same antenna for transmission and reception.

[0004] However, each duplexer is designed for a specific frequency band, meaning that a single duplexer can only support a fixed pair of TX / RX frequency bands. Therefore, when a terminal needs to support multiple FDD frequency bands (such as B1, B2, B3, etc.), an independent duplexer and corresponding RF path must be configured for each frequency band, resulting in complex RF front-end circuitry, large footprint, and high material costs.

[0025] In wireless communication systems, the radio frequency (RF) front-end is a crucial component for signal transmission and reception. Currently, FDD uses two independent but symmetrical frequency channels for TX and RX communication, respectively. Traditional FDD typically employs duplexers to isolate transmit and receive signals. However, each duplexer is designed for a specific frequency band. When a terminal needs to support multiple FDD frequency bands, an independent duplexer and corresponding RF path must be configured for each band, resulting in complex RF front-end circuitry, large footprint, and high material costs. In other words, existing technologies for the architecture design of RF front-ends in mobile terminal devices have certain limitations.

[0026] Based on the above-mentioned problems, this application provides a radio frequency transceiver system that, without using a duplexer for frequency division, simultaneously opens a pair of transceiver ports in the transceiver conduction module, achieves frequency division transceiver effect through a transceiver wideband filtering module, and simplifies the radio frequency front-end architecture.

[0027] Figure 1 Schematic diagram of the radio frequency transceiver system provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, the radio frequency transceiver system includes: a driver module 1, a transceiver module 2, a transceiver wideband filtering module 3, a transceiver conduction module 4, and an antenna.

[0028] Optionally, refer to Figure 1 The radio frequency transceiver system transmits and receives signals through driver module 1, transceiver module 2, transceiver broadband filter module 3, transceiver conduction module 4 and antenna. Among them, the radio frequency transceiver system receives signals as a primary receiver (PRX).

[0029] Transceiver module 2 is connected to the first end of transceiver broadband filter module 3, and the second end of transceiver broadband filter module 3 is connected to one end of transceiver conduction module 4, which is located within the antenna's radiation area. Driver module 1 is connected to both transceiver module 2 and transceiver conduction module 4.

[0030] Optionally, continue to refer to Figure 1The first and second ends of the transceiver broadband filtering module 3 are connected to the transceiver module 2 and the transceiver conduction module 4, respectively, so as to transmit received signals to the transceiver module 2 in the receiving channel formed by the transceiver conduction module 4, and receive transmitted signals from the transceiver module 2 in the transmitting channel formed by the transceiver conduction module 4. The transceiver conduction module 4 is located in the radiation area of ​​the antenna. The antenna, as the exit of the transmitting channel, converts the signal transmitted by the transceiver module 2 into electromagnetic waves for outward radiation, and as the entrance of the receiving channel, receives electromagnetic waves radiated by the external base station, converts them into received signals, and transmits them to the transceiver module 2. The driving module 1 is connected to the transceiver module 2 and the transceiver conduction module 4, respectively, to drive the transceiver conduction module 4 to form a transmitting channel based on the signal to be transmitted from the transceiver module 2, and to drive the transceiver conduction module 4 to form a receiving channel based on the signal to be received radiated and converted by the antenna.

[0031] Transceiver module 2 is used to receive signals from external devices and send signals to external devices via transceiver broadband filtering module 3, transceiver conduction module 4, and antenna. Transceiver conduction module 4 is used to form a transmission channel and a reception channel under the drive of drive module 1.

[0032] Optionally, continue to refer to Figure 1 Under the drive of the driving module 1, the transceiver module 4 forms a transmit channel and a receive channel. The transceiver module 2 transmits signals to external devices through the transmit channel via the transceiver broadband filter module 3, the transceiver module 4, and the antenna. For example, the external device can be a base station. While transmitting signals to external devices through the transmit channel, the transceiver module 2 also receives signals from external devices through the receive channel via the transceiver broadband filter module 3, the transceiver module 4, and the antenna.

[0033] The transceiver broadband filter module 3 is used in the transmission channel to output the transmitted signal from the transceiver module 2 to the transceiver conduction module 4 located in the radiation area of ​​the antenna, so that the antenna radiates the transmitted signal to external devices; the transceiver broadband filter module 3 is also used in the receiving channel to output the received signal radiated by the antenna and transmitted through the transceiver conduction module 4 to the transceiver module 2.

[0034] Optionally, continue to refer to Figure 1 In the transmit channel, the wideband filtering module 3 receives the transmitted signal from the transceiver module 2, filters out out-of-band clutter using its wideband filtering characteristics, and transmits the filtered transmitted signal to the transceiver conduction module 4 within the antenna radiation area. The antenna then converts the filtered transmitted signal into electromagnetic waves and radiates them to external devices. Simultaneously, in the receive channel, the wideband filtering module 3 receives the received signal captured by the antenna and transmitted by the transceiver conduction module 4, filters out out-of-band clutter using its wideband filtering characteristics, and transmits the filtered received signal to the transceiver module 2.

[0035] Among them, the wideband filtering performance of the transceiver wideband filtering module 3 can replace the frequency band isolation function of the duplexer. Without relying on the duplexer, the transceiver wideband filtering module 3 enables independent parallel transmission of transmitted and received signals in the frequency division duplex architecture. In other words, the transmit and receive channels can work independently and in parallel, allowing the RF transceiver system to simultaneously receive signals from external devices such as base stations while transmitting signals, thus achieving the frequency division duplex effect without relying on the duplexer.

[0036] In this embodiment, the radio frequency transceiver system includes a driver module, a transceiver module, a transceiver broadband filtering module, a transceiver conduction module, and an antenna. The transceiver conduction module, driven by the driver module, forms a transmit channel and a receive channel. The transceiver module transmits signals to external devices through the transmit channel via the transceiver broadband filtering module, the transceiver conduction module, and the antenna. Simultaneously, it receives signals from external devices through the receive channel via the transceiver broadband filtering module, the transceiver conduction module, and the antenna. In the transmit channel, the transceiver broadband filtering module outputs the transmitted signal from the transceiver module to the transceiver conduction module located within the antenna's radiation area, enabling the antenna to radiate the transmitted signal outwards to the external device. In the receive channel, it also outputs the received signal radiated by the antenna and transmitted through the transceiver conduction module back to the transceiver module. Based on the wideband filtering performance of the transceiver wideband filter module, the frequency band isolation function of the duplexer is replaced. Without relying on the duplexer, the independent parallel transmission of the transmitted and received signals in the frequency division duplex architecture is achieved through the transceiver wideband filter module. This allows the RF transceiver system to simultaneously receive signals from external devices such as base stations while transmitting signals to the outside world, thus achieving the effect of frequency division duplex and simplifying the architecture of the RF transceiver system.

[0037] Figure 2 Schematic diagram of the radio frequency transceiver system provided in the embodiments of this application Figure 2 ,like Figure 2 As shown, the transceiver broadband filtering module 3 includes: a transmit channel broadband filtering unit 31 and a first receive channel broadband filtering unit 32.

[0038] Optionally, refer to Figure 2 The transceiver broadband filtering module 3 includes a transmit channel broadband filtering unit 31 and a first receive channel broadband filtering unit 32. The transceiver module 2 transmits signals to external devices through the transmit channel via the transmit channel broadband filtering unit 31, the transceiver conduction module 4 and the antenna. At the same time, it receives signals from external devices through the receive channel via the first receive channel broadband filtering unit 32, the transceiver conduction module 4 and the antenna.

[0039] The input terminal of the transmit channel wideband filter unit 31 is connected to the output terminal of the transceiver module 2, and the output terminal of the transmit channel wideband filter unit 31 is connected to one end of the transceiver conduction module 4.

[0040] Optionally, continue to refer to Figure 2 The input terminal of the transmit channel wideband filter unit 31 is connected to the output terminal TX of the transceiver module 2, and the output terminal is connected to one end of the transceiver conduction module 4.

[0041] In the transmission channel, the broadband filtering unit 31 receives the transmitted signal from the transceiver module 2, filters out out-of-band clutter through broadband filtering characteristics, and transmits the filtered transmitted signal to the transceiver conduction module 4 in the antenna radiation area. The antenna converts the filtered transmitted signal into electromagnetic waves and radiates them to external devices.

[0042] The input terminal of the first receiving channel wideband filtering unit 32 is connected to one end of the transceiver module 4, and the output terminal of the first receiving channel wideband filtering unit 32 is connected to the input terminal of the transceiver module 2.

[0043] Optionally, continue to refer to Figure 2 The input terminal of the first receiving channel wideband filtering unit 32 is connected to one end of the transceiver module 4, and the output terminal is connected to the input terminal PRX of the transceiver module 2.

[0044] The first receiving channel broadband filtering unit 32 and the transmitting channel broadband filtering unit 31 work independently and in parallel. While the transmitting channel broadband filtering unit 31 filters and transmits the transmitted signal, the first receiving channel broadband filtering unit 32 receives the received signal transmitted by the antenna acquisition and transceiver module 4 in the receiving channel, filters out out-of-band clutter through the broadband filtering characteristics, and transmits the filtered received signal to the transceiver module 2.

[0045] In this embodiment, the transceiver broadband filtering module includes a transmit channel broadband filtering unit and a first receive channel broadband filtering unit. The transmit channel broadband filtering unit, located in the transmit channel, receives the transmitted signal from the transceiver module, filters out out-of-band clutter using broadband filtering characteristics, and transmits the filtered transmitted signal to the transceiver conduction module within the antenna radiation area. The antenna then converts the filtered transmitted signal into electromagnetic waves and radiates them to external devices. The first receive channel broadband filtering unit operates independently and in parallel with the transmit channel broadband filtering unit. Located in the receive channel, the first receive channel broadband filtering unit receives the received signal captured by the antenna and transmitted by the transceiver conduction module, filters out out-of-band clutter using broadband filtering characteristics, and transmits the filtered received signal to the transceiver module. The transmit channel broadband filtering unit and the first receive channel broadband filtering unit achieve frequency division duplexing.

[0046] As an optional implementation, the radio frequency transceiver system also includes: a power amplifier module 5.

[0047] Optionally, continue to refer to Figure 2In the radio frequency transceiver system, a power amplifier module 5 is set between the transceiver module 2 and the transmit channel broadband filter unit 31 to amplify the transmit signal output by the transceiver module 2 and transmit it to the transmit channel broadband filter unit 31.

[0048] The input terminal of the power amplifier module 5 is connected to the output terminal of the transceiver module 2, and the output terminal of the power amplifier module 5 is connected to the input terminal of the transmit channel broadband filter unit 31. The power amplifier module 5 is used to amplify the transmit signal from the transceiver module 2 and output the amplified transmit signal to the transmit channel broadband filter unit 31.

[0049] Optionally, continue to refer to Figure 2 The input of power amplifier module 5 is connected to the output (TX) of transceiver module 2 to receive the transmitted signal from transceiver module 2. Since the transmitted signal from transceiver module 2 has low power, it can only meet short-distance transmission requirements and cannot directly drive the antenna for long-distance radiation. Power amplifier module 5 amplifies the transmitted signal to obtain the amplified transmitted signal. The output of power amplifier module 5 is connected to the input of transmit channel broadband filter unit 31 to transmit the amplified transmitted signal to the transmit channel broadband filter unit 31. This allows the amplified transmitted signal to drive the antenna for long-distance radiation, avoiding the problem of the transmitted signal rapidly attenuating over long distances due to insufficient power, which would prevent external devices from recognizing it.

[0050] In this embodiment, the radio frequency transceiver system includes a power amplification module, which is disposed between the transceiver module and the transmit channel broadband filter unit. The power amplification module amplifies the transmitted signal from the transceiver module and outputs the amplified transmitted signal to the transmit channel broadband filter unit. This allows the amplified transmitted signal to drive the antenna to achieve long-distance radiation, avoiding the problem of the transmitted signal rapidly attenuating over long distances due to insufficient power, which would prevent external devices from recognizing it.

[0051] Figure 3 Schematic diagram of the radio frequency transceiver system provided in the embodiments of this application Figure 3 ,like Figure 3 As shown, the transmit channel wideband filtering unit 31 includes multiple transmit channel wideband filters.

[0052] Optionally, the transmit channel broadband filtering unit 31 includes multiple transmit channel broadband filters, each of which is a bandpass filter. The passbands of each transmit channel broadband filter are different, meaning each transmit channel broadband filter corresponds to a different transmit frequency band. Figure 3 For example, the transmit channel broadband filtering unit 31 includes filter A, filter B and filter C.

[0053] The input terminal of each transmit channel broadband filter is connected to the output terminal of the power amplifier module 5, and the output terminal of each transmit channel broadband filter is connected to one end of the transmit / receive module 4.

[0054] Optionally, continue to refer to Figure 3 The input terminals of each transmit channel broadband filter are connected to the output terminals of the power amplifier module 5 to receive transmit signals of different frequency bands emitted by the transceiver module 2. The output terminals of each transmit channel broadband filter are connected to one end of the transceiver conduction module 4, so that the transmit signals of different frequency bands emitted by the transceiver module 2 can be transmitted to the transceiver conduction module 4 through the corresponding transmit channel broadband filter.

[0055] Each transmit channel broadband filter corresponds to at least one transmit frequency band. The transmit channel broadband filter is used to output the transmit signal in the transmit frequency band corresponding to the transmit channel broadband filter to the transceiver module 4 located in the radiation area of ​​the antenna.

[0056] Optionally, each transmit channel broadband filter corresponds to at least one transmit frequency band.

[0057] Table 1 shows the frequency distribution of each transmitting and receiving frequency band. Each transmitting and receiving frequency band in Table 1 is only an example, and this application does not impose specific restrictions on the number of receiving and transmitting frequency bands.

[0058] Taking the B1 / B2 / B3 / B4 / B25 / B66 frequency bands in Table 1 as an example, the distribution of the TX and RX frequency bands of the B1 / B2 / B3 / B4 / B25 / B66 frequency bands is shown in Table 1 below.

[0059] Table 1

[0060] Various types of broadband filters are configured according to frequency bands. Figure 4 This is a schematic diagram of the transmit and receive frequency bands of various broadband filters provided in the embodiments of this application, as shown below. Figure 4 As shown, blue represents the transmit band (TX band), and orange represents the receive band (RX band). Specifically, the first wideband filter corresponds to the transmit bands of B3 / B4 / B66, i.e., B3T / B4T / B66T. The second wideband filter corresponds to the receive band of B3 and the transmit bands of B2 / B25, i.e., B3R / B2T / B25T. The third wideband filter corresponds to the receive bands of B2 / B25 and the transmit band of B1, i.e., B2R / B25R / B1T. The fourth wideband filter corresponds to the receive bands of B1 / B4 / B66, i.e., B1R / B4R / B66R. Figure 3In the transmit channel wideband filtering unit 31, filter A is a first wideband filter, and the corresponding transmit frequency band is B3T / B4T / B66T. Filter B is a second wideband filter, and the corresponding transmit frequency band is B2T / B25T. Filter C is a third wideband filter, and the corresponding transmit frequency band is B1T.

[0061] It is worth noting that, Figure 3 The number of broadband filters in the transmission channel is not limited to filter A, filter B, and filter C. It can be determined according to the frequency band of the signal transmitted by transceiver module 2 during cellular communication.

[0062] The transmit channel broadband filter outputs the transmit signal within the corresponding transmit frequency band of the transmit channel broadband filter to the transceiver module 4 located within the antenna's radiation area via the passband. Figure 3 Taking filter A as an example, when the RF transceiver system is operating in the B3 band, the transmit signal emitted by transceiver module 2 belongs to the B3T band. The passband of filter A allows the transmit signal of the B3T band to be output to the transceiver module 4 located in the radiation area of ​​the antenna.

[0063] In this embodiment, the transmit channel broadband filtering unit includes multiple transmit channel broadband filters, each of which corresponds to at least one transmit frequency band. The transmit channel broadband filter outputs the transmit signal within the transmit frequency band corresponding to the transmit channel broadband filter to the transceiver module located in the radiation area of ​​the antenna.

[0064] As an optional implementation, the first receiving channel wideband filtering unit 32 includes a plurality of first receiving channel wideband filters.

[0065] Optionally, the first receiving channel wideband filtering unit 32 includes multiple first receiving channel wideband filters, each of which is a bandpass filter. The passbands of each first receiving channel wideband filter are different, meaning each first receiving channel wideband filter corresponds to a different receiving frequency band. Figure 3 For example, the first receiving channel wideband filtering unit 32 includes filter D, filter E and filter F.

[0066] The input terminal of each first receiving channel wideband filter is connected to one end of the transceiver module 4, and the output terminal of each first receiving channel wideband filter is connected to the input terminal of the transceiver module 2.

[0067] Optionally, continue to refer to Figure 3Each first receiving channel broadband filter's input terminal is connected to one end of the transceiver module 4 to receive different frequency band signals transmitted by the transceiver module 4. Each first receiving channel broadband filter's output terminal is connected to the input terminal of the transceiver module 2 to transmit the different frequency band signals to the transceiver module 2's input terminal PRX. For example, Figure 3 The output terminals of filters D, E, and F are respectively connected to the first input terminal PRX1, the second input terminal PRX2, and the third input terminal PRX3 of transceiver module 2.

[0068] It is worth noting that, Figure 3 The number of broadband filters in the first receiving channel is not limited to filter D, filter E and filter F. It can be determined according to the frequency band of the signal received by transceiver module 2 during cellular communication.

[0069] Each first receiving channel wideband filter corresponds to at least one receiving frequency band. The first receiving channel wideband filter is used to output the received signal within the receiving frequency band corresponding to the first receiving channel wideband filter to the transceiver module 2.

[0070] Optionally, each first receiving channel broadband filter corresponds to at least one receiving frequency band, in conjunction with Table 1 above. Figure 4 , Figure 3 In the first receiving channel wideband filtering unit 32, filter D is a fourth wideband filter, and the receiving frequency band corresponding to filter D is B1R / B4R / B66R. Filter E is a third wideband filter, and the receiving frequency band corresponding to filter E is B2R / B25R. Filter F is a second wideband filter, and the receiving frequency band corresponding to filter F is B3R.

[0071] The first receiving channel wideband filter outputs the received signal within the corresponding receiving frequency band to transceiver module 2 via the passband. Figure 3 Taking filter F as an example, when the RF transceiver system is operating in the B3 band, the frequency band of the received signal to be received is B3R. The passband of filter F allows the received signal in the B3R band to be output to transceiver module 2.

[0072] In this embodiment, the first receiving channel wideband filtering unit includes multiple first receiving channel wideband filters, each of which corresponds to at least one receiving frequency band. The first receiving channel wideband filter outputs the received signal within the receiving frequency band corresponding to the first receiving channel wideband filter to the transceiver module.

[0073] As an optional implementation, the transceiver module 4 includes multiple receiving ports and multiple transmitting ports.

[0074] Each receiving port and each transmitting port of the transceiver module 4 is connected to the second end of the transceiver broadband filter module 3.

[0075] Optionally, the transceiver module 4 includes multiple receive ports (RP) and multiple transmit ports (TP). Figure 3 For example, the transceiver module 4 includes a first transmitting port TP1, a second transmitting port TP2, and a third transmitting port TP3, which are respectively connected to filters A, B, and C in the transmit channel broadband filtering unit 31. The transceiver module 4 also includes a first receiving port RP1, a second receiving port RP2, and a third receiving port RP3, which are respectively connected to filters D, E, and F in the first receive channel broadband filtering unit 32.

[0076] The driving module 1 is used to send a first driving signal to the transceiver activation module 4 according to the frequency band of the signal to be transmitted by the transceiver module 2. The transceiver activation module 4 is used to activate the transmission port corresponding to the frequency band of the signal to be transmitted under the action of the first driving signal, so as to form a transmission channel corresponding to the signal to be transmitted.

[0077] Optionally, before the transceiver module 2 transmits a signal, the drive module 1 generates a first drive signal based on the frequency band of the signal to be transmitted from the transceiver module 2. The first drive signal is used to instruct the transceiver activation module 4 to activate the transmission port corresponding to the frequency band of the signal to be transmitted. Under the action of the first drive signal, the transceiver activation module 4 activates the transmission port corresponding to the frequency band of the signal to be transmitted, thereby forming a transmission channel corresponding to the signal to be transmitted. This facilitates the transmission channel broadband filter connected to the activated transmission port to transmit the transmitted signal from the transceiver module 2 to the transceiver activation module 4 through the activated transmission port.

[0078] For example, when the RF transceiver system operates in the B3 band, the transmitted signal frequency band is B3T. The driver module 1 generates a first drive signal and outputs it to the transceiver activation module 4. The first drive signal instructs the transceiver activation module 4 to activate the first transmit port TP1. Under the action of the first drive signal, the transceiver activation module 4 activates the first transmit port TP1, forming a transmission channel corresponding to the signal to be transmitted in the B3T band. This facilitates the filter A connected to the activated first transmit port TP1 to transmit the B3T band transmitted signal from the transceiver module 2 to the transceiver activation module 4 through the activated first transmit port TP1.

[0079] The transceiver module 4 is also used to output the signal to be received radiated by the antenna to the drive module 1. The drive module 1 is also used to send a second drive signal to the transceiver module 4 according to the signal to be received. The transceiver module 4 is also used to turn on the receiving port corresponding to the frequency band to which the signal to be received belongs under the action of the second drive signal, so as to form a receiving channel corresponding to the signal to be received.

[0080] Optionally, the transceiver module 4 outputs the signal to be received radiated by the antenna to the drive module 1. The drive module 1 generates a second drive signal according to the frequency band of the signal to be received and outputs it to the transceiver module 4. The second drive signal is used to instruct the transceiver module 4 to activate the receiving port corresponding to the frequency band of the signal to be received. Under the action of the second drive signal, the transceiver module 4 activates the receiving port corresponding to the frequency band of the signal to be received, thereby forming a receiving channel corresponding to the signal to be received. This facilitates the transmission of the received signal radiated by the antenna to the transceiver module 2 through the activated receiving port via the first receiving channel broadband filter connected to the activated receiving port.

[0081] For example, when the RF transceiver system operates in the B3 band, and the frequency band of the signal to be received radiated by the antenna is B3R, then the driving module 1 generates a second driving signal and outputs it to the transceiver activation module 4. The second driving signal is used to instruct the transceiver activation module 4 to activate the third receiving port RP3. Under the action of the second driving signal, the transceiver activation module 4 activates the third receiving port RP3 to form a receiving channel corresponding to the signal to be received in the B3R band. This allows the filter F connected to the activated third receiving port RP3 to transmit the received signal in the B3R band radiated by the antenna to the transceiver module 2 through the activated third receiving port RP3.

[0082] In this embodiment, the transceiver module includes multiple receiving ports and multiple transmitting ports. The driving module sends a first driving signal to the transceiver module according to the frequency band of the signal to be transmitted. Under the action of the first driving signal, the transceiver module turns on the transmitting port corresponding to the frequency band of the signal to be transmitted, thereby forming a transmission channel corresponding to the signal to be transmitted. This facilitates the transmission channel broadband filter connected to the turned-on transmitting port to transmit the transmitted signal emitted by the transceiver module to the transceiver module through the turned-on transmitting port. The transceiver module outputs the signal to be received radiated by the antenna to the driving module. The driving module sends a second driving signal to the transceiver module according to the signal to be received. Under the action of the second driving signal, the transceiver module turns on the receiving port corresponding to the frequency band of the signal to be received, thereby forming a receiving channel corresponding to the signal to be received. This facilitates the first receiving channel broadband filter connected to the turned-on receiving port to transmit the received signal radiated by the antenna to the transceiver module through the turned-on receiving port.

[0083] As an optional implementation, the transceiver module 4 also includes a transceiver selection switch K1.

[0084] The transmit / receive gating switch K1 is located within the antenna's radiation area. The control terminal of the transmit / receive gating switch K1 is connected to the drive module 1. The selection terminal of the transmit / receive gating switch K1 can be switched to the output terminal of each transmit channel broadband filter unit 31 through each transmit port, and can be switched to the input terminal of each first receive channel broadband filter unit 32 through each receive port.

[0085] Optionally, the transceiver activation module 4 also includes a transceiver gating switch K1, which is located within the radiation area of ​​the antenna. The transceiver gating switch K1 includes a control terminal and multiple selection terminals. The multiple selection terminals of the transceiver gating switch K1 can be switchedly connected to each transmit channel broadband filter unit 31 through each transmit port, and can be switchedly connected to each first receive channel broadband filter unit 32 through each receive port.

[0086] by Figure 3 For example, the transmit / receive gating switch K1 includes one control terminal and six selection terminals. The control terminal of the transmit / receive gating switch K1 is connected to the drive module 1 to receive the first drive signal and the second drive signal sent by the drive module 1.

[0087] The six selection terminals of the transmit / receive gating switch K1 are selectively connected to filters A, B, C, D, E, and F through the first transmit port TP1, the second transmit port TP2, the third transmit port TP3, the first receive port RP1, the second receive port RP2, and the third receive port RP3, respectively.

[0088] The transmit / receive gating switch K1 is used to close to the transmit port corresponding to the frequency band of the signal to be transmitted under the action of the first driving signal. The transmit / receive gating switch K1 is also used to close to the receive port corresponding to the frequency band of the signal to be received under the action of the second driving signal.

[0089] Optionally, the transmit / receive gating switch K1 is closed to the transmit port corresponding to the frequency band of the signal to be transmitted under the action of the first driving signal, and closed to the receive port corresponding to the frequency band of the signal to be received under the action of the second driving signal.

[0090] by Figure 3 For example, when the RF transceiver system operates in the B3 band, the transmit / receive gating switch K1 closes to the first transmit port TP1 corresponding to the B3T band under the action of the first driving signal, forming a transmit channel for transmitting transmit signals in the B3T band. Under the action of the second driving signal, the transmit / receive gating switch K1 closes to the third receive port RP3 corresponding to the B3R band, forming a receive channel for transmitting receive signals in the B3R band.

[0091] In this embodiment, the transceiver activation module further includes a transceiver selection switch located within the antenna's radiation area. The control terminal of the transceiver selection switch is connected to the drive module. Each selection terminal is switchably connected to the output terminal of each transmit channel broadband filter unit via each transmit port, and switchably connected to the input terminal of each first receive channel broadband filter unit via each receive port. Under the action of a first drive signal, the transceiver selection switch closes to the transmit port corresponding to the frequency band of the signal to be transmitted, and under the action of a second drive signal, closes to the receive port corresponding to the frequency band of the signal to be received, thus forming a transmit channel and a receive channel.

[0094] The diversity receiving module 7 is connected to the first end of the receiving broadband filtering module 8, and the second end of the receiving broadband filtering module 8 is connected to one end of the receiving conduction module 9, which is located within the radiation area of ​​the diversity antenna. The receiving drive module 6 is connected to the receiving conduction module 9.

[0095] Optionally, continue to refer to Figure 5 The first and second ends of the receiving broadband filtering module 8 are connected to the diversity receiving module 7 and the receiving conduction module 9, respectively, so as to transmit the received signal to the diversity receiving module 7 in the diversity receiving channel formed by the receiving conduction module 9. The receiving conduction module 9 is located in the radiation area of ​​the diversity antenna. The diversity antenna, as the entrance to the diversity receiving channel, receives electromagnetic waves radiated by external devices and converts them into received signals for transmission to the diversity receiving module 7. The receiving drive module 6 is connected to the receiving conduction module 9 to drive the receiving conduction module 9 to form a diversity receiving channel based on the signal to be received radiated and converted by the diversity antenna.

[0096] Diversity receiving module 7 is used to receive signals from external devices via receiving broadband filtering module 8, receiving conduction module 9, and diversity antenna. Receiving conduction module 9 is used to form a diversity receiving channel under the drive of receiving drive module 6.

[0097] Optionally, continue to refer to Figure 5 Under the drive of the receiving drive module 6, the receiving conduction module 9 forms a diversity receiving channel. The diversity receiving module 7 receives signals from external devices through the diversity receiving channel via the receiving broadband filter module 8, the receiving conduction module 9 and the diversity antenna.

[0098] The receiving broadband filtering module 8 is used to output the received signal radiated by the diversity antenna and transmitted via the receiving conduction module 9 to the diversity receiving module 7 in the diversity receiving channel.

[0099] Optionally, the wideband filtering module 8 receives the received signal captured by the diversity antenna and transmitted by the receive conduction module 9 in the diversity receiving channel, filters out out-of-band clutter through the wideband filtering characteristics, and transmits the filtered received signal to the diversity receiving module 7.

[0100] In this embodiment, the RF receiving system includes a receive driver module, a diversity receiving module, a receive wideband filtering module, a receive conduction module, and a diversity antenna. The receive conduction module, driven by the receive driver module, forms a diversity receiving channel. The diversity receiving module receives signals from external devices through the diversity receiving channel via the receive wideband filtering module, the receive conduction module, and the diversity antenna. The receive wideband filtering module, within the diversity receiving channel, outputs the received signal radiated by the diversity antenna and transmitted via the receive conduction module to the diversity receiving module. This simplifies the architecture of the RF receiving system and achieves diversity receiving functionality.

[0101] Figure 6 Schematic diagram of the radio frequency receiving system provided in the embodiments of this application Figure 2 ,like Figure 6 As shown, the receiving wideband filtering module 8 includes: a second receiving channel wideband filtering unit 81.

[0102] Optionally, refer to Figure 6 The receiving wideband filtering module 8 includes a second receiving channel wideband filtering unit 81. The diversity receiving module 7 receives signals from external devices through the diversity receiving channel via the second receiving channel wideband filtering unit 81, the receiving conduction module 9, and the diversity antenna.

[0103] The input terminal of the second receiving channel wideband filtering unit 81 is connected to one end of the receiving conduction module 9, and the output terminal of the second receiving channel wideband filtering unit 81 is connected to the input terminal of the diversity receiving module 7.

[0104] Optionally, continue to refer to Figure 6 The input terminal of the second receiving channel wideband filtering unit 81 is connected to one end of the receiving conduction module 9, and the output terminal is connected to the input terminal DRX of the diversity receiving module 7.

[0105] In the diversity receiving channel, the second receiving channel wideband filtering unit 81 receives the received signal captured by the diversity antenna and transmitted by the receiving conduction module 9, filters out out-of-band clutter through wideband filtering characteristics, and transmits the filtered received signal to the diversity receiving module 7.

[0106] In this embodiment, the receiving broadband filtering module includes a second receiving channel broadband filtering unit. The input of the second receiving channel broadband filtering unit is connected to one end of the receiving conduction module, and the output is connected to the input of the diversity receiving module. In the diversity receiving channel, the second receiving channel broadband filtering unit receives the received signal captured by the diversity antenna and transmitted by the receiving conduction module, filters out out-of-band clutter using broadband filtering characteristics, and transmits the filtered received signal to the diversity receiving module. The diversity receiving function is achieved through the second receiving channel broadband filtering unit in the receiving broadband filtering module.

[0107] Figure 7 Schematic diagram of the radio frequency receiving system provided in the embodiments of this application Figure 3 ,like Figure 7 As shown, the second receiving channel wideband filtering unit 81 includes multiple second receiving channel wideband filters.

[0108] Optionally, the second receiving channel wideband filtering unit 81 includes multiple second receiving channel wideband filters, each of which is a bandpass filter. The passbands of each second receiving channel wideband filter are different, meaning that each second receiving channel wideband filter corresponds to a different diversity receiving frequency band. Figure 7 For example, the second receiving channel wideband filtering unit 81 includes filter G, filter H and filter I.

[0109] The input terminal of each second receiving channel broadband filter is connected to one end of the receiving conduction module 9, and the output terminal of each second receiving channel broadband filter is connected to the input terminal of the diversity receiving module 7.

[0110] Optionally, continue to refer to Figure 7 Each second receiving channel broadband filter's input terminal is connected to one end of the receiving conduction module 9 to receive different frequency band signals transmitted by the receiving conduction module 9. Each second receiving channel broadband filter's output terminal is connected to the input terminal of the diversity receiving module 7 to transmit the different frequency band signals to the DRX input terminal of the diversity receiving module 7. For example, Figure 7 The outputs of filters G, H and I are connected to the first input DRX1, the second input DRX2 and the third input DRX3 of the diversity receiving module 7, respectively.

[0111] It is worth noting that, Figure 7The number of broadband filters in the second receiving channel is not limited to filter G, filter H and filter I. It can be determined according to the frequency band of the signal received by the diversity receiving module 7 during cellular communication.

[0112] Each second receiving channel wideband filter corresponds to at least one diversity receiving frequency band. The second receiving channel wideband filter is used to output the received signal within the receiving frequency band corresponding to the second receiving channel wideband filter to the diversity receiving module 7.

[0113] Optionally, each second receiving channel broadband filter corresponds to at least one diversity receiving frequency band, in conjunction with Table 1 above. Figure 4 , Figure 7 In the second receiving channel wideband filtering unit 81, filter G is a fourth wideband filter, and the corresponding diversity receiving frequency bands are B1R / B4R / B66R. Filter H is a third wideband filter, and the corresponding diversity receiving frequency bands are B2R / B25R. Filter I is a second wideband filter, and the corresponding diversity receiving frequency band is B3R.

[0114] The second receiving channel wideband filter outputs the received signal within the corresponding receiving frequency band to the diversity receiving module 7 via the passband. Figure 7 Taking filter I as an example, when the RF receiving system is operating in the B3 band, the frequency band of the received signal to be received is B3R. The passband of filter I allows the received signal in the B3R band to be output to the diversity receiving module 7.

[0115] In this embodiment, the second receiving channel wideband filtering unit includes multiple second receiving channel wideband filters. Each second receiving channel wideband filter corresponds to at least one diversity receiving frequency band. The second receiving channel wideband filter outputs the received signal within the receiving frequency band corresponding to the second receiving channel wideband filter to the diversity receiving module.

[0116] Continue according to Figure 7 The receiver activation module 9 includes multiple receiver ports. Each receiver port of the receiver activation module 9 is connected to the receiver broadband filtering module 8. For example, Figure 7 The receiving module 9 includes a fourth receiving port RP4, a fifth receiving port RP5, and a sixth receiving port RP6, which are respectively connected to filters G, H, and I in the second receiving broadband filtering unit.

[0117] The receiving activation module 9 is used to output the signal to be received radiated by the diversity antenna to the receiving drive module 6. The receiving drive module 6 is used to send a third drive signal to the receiving activation module 9 according to the signal to be received. The receiving activation module 9 is used to activate the receiving port corresponding to the frequency band to which the signal to be received belongs under the action of the third drive signal, so as to form a diversity receiving channel corresponding to the signal to be received.

[0118] Specifically, the receiving activation module 9 outputs the signal to be received radiated by the diversity antenna to the receiving drive module 6. The receiving drive module 6 generates a third drive signal based on the frequency band of the signal to be received and outputs it to the receiving activation module 9. The third drive signal instructs the receiving activation module 9 to activate the receiving port corresponding to the frequency band of the signal to be received. Under the action of the third drive signal, the receiving activation module 9 activates the receiving port corresponding to the frequency band of the signal to be received, thereby forming a diversity receiving channel corresponding to the signal to be received. This facilitates the transmission of the received signal radiated by the diversity antenna to the diversity receiving module 7 through the activated receiving port via the second receiving channel broadband filter connected to the activated receiving port.

[0119] For example, when the RF receiving system operates in the B3 band, and the frequency band of the signal to be received radiated by the diversity antenna is B3R, the receiving drive module 6 generates a third drive signal and outputs it to the receiving conduction module 9. The third drive signal is used to instruct the receiving conduction module 9 to conduct the sixth receiving port RP6. Under the action of the third drive signal, the receiving conduction module 9 conducts the sixth receiving port RP6 to form a diversity receiving channel corresponding to the signal to be received in the B3R band. This facilitates the filter I connected to the conducted sixth receiving port RP6 to transmit the received signal in the B3R band radiated by the diversity antenna to the diversity receiving module 7 through the conducted sixth receiving port RP6.

[0120] Continue according to Figure 7 The receiver conduction module 9 also includes a receiver gating switch K2, which is located within the radiation area of ​​the diversity antenna. The receiver gating switch K2 includes a control terminal and multiple selection terminals. The multiple selection terminals of the receiver gating switch K2 are switchably connected to each of the second receiver channel broadband filtering units 81 through each receiver port.

[0121] by Figure 7 For example, the receive gating switch K2 includes one control terminal and three selection terminals. The control terminal of the receive gating switch K2 is connected to the receive driver module 6 to receive the third drive signal sent by the receive driver module 6. The three selection terminals of the receive gating switch K2 are selectively connected to filters G, H, and I through the fourth receive port RP4, the fifth receive port RP5, and the sixth receive port RP6, respectively.

[0122] The receive gating switch K2 is used to close to the receiving port corresponding to the frequency band of the signal to be received under the action of the third driving signal. Figure 7 For example, when the radio frequency receiving system is operating in the B3 band, the receive gating switch K2 is closed to the sixth receiving port RP6 corresponding to the B3R band under the action of the third driving signal, forming a diversity receiving channel for transmitting the received signal of the B3R band.

[0123] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
