[0096] The RF device involved in the embodiments of the present application may be an FEM (Front-end Module), and further optionally, the RF device may be a WIFI FEM, i.e., a front-end integrated module for WIFI. The RF device may be connected to an RF transceiver and an antenna to support the transmission of a first communication signal.

[0097] FIG1 is a block diagram of a radio frequency device 10 according to an embodiment. Referring to FIG1 , in this embodiment, the radio frequency device 10 is configured with a transmit port (e.g., the TX port) for connecting to a radio frequency transceiver 20 and an antenna port (e.g., the ANT port) for connecting to an antenna (e.g., the ANT port). The radio frequency device includes a first transmit path 100 and a second transmit path 200 that are conductively connected to the antenna port (the figure illustrates only a common connection between the two transmit paths and the antenna port, which is not limited to this connection method). Furthermore, the device includes a first gating circuit 300.

[0098] The RF device can be understood as a package structure, and the transmit port and antenna port can be understood as RF pin terminals of the package structure, which are used to connect to various external devices. The transmit port is used to receive communication signals to be transmitted from the RF transceiver 20. The RF device can transmit the input RF transceiver 20 to the antenna port, and then transmit it through the antenna connected to the antenna port to achieve transmission control of the communication signal.

[0099] The first transmit path 100 is used to amplify and filter the first communication signal; the second transmit path 200 is used to amplify the first communication signal. The first transmit path 100 not only amplifies the signal but also provides additional filtering to meet high-power communication requirements. The second transmit path 200 amplifies the signal, has sufficient linearity and sufficient harmonic margin to eliminate the need for filtering. This eliminates the need for additional filtering, thus saving unnecessary losses and meeting the requirements of high-signal-strength communication. Therefore, different transmit paths can support transmission processing with different signal level requirements, adapting to different communication needs.

[0100] The first end of the first gating circuit 300 is connected to the transmit port, and the multiple second ends of the first gating circuit 300 are respectively connected to the first transmit path 100 and the second transmit path 200. The first gating circuit 300 and the second gating circuit 400 are used to selectively connect a target transmit path with the RF transceiver 20. The target transmit path includes one of the first transmit path 100 and the second transmit path 200.

[0101] The first gating circuit 300 is connected to the RF transceiver 20, the first transmission path 100, and the second transmission path 200, respectively. Thus, through the gating function of the first gating circuit 300, the RF transceiver 20 can be switchably connected to the target transmission path, thereby realizing the transmission path selection switching function; optionally, the first gating circuit 300 can be a single-pole multi-throw switch or a multi-pole multi-throw switch.

[0102] The first selection circuit 300 can selectively conduct the target transmission path between the RF transceiver 20 and the antenna, so that any channel of the first transmission path 100 and the second transmission path 200 can perform transmission processing on the first communication signal to be transmitted under different communication requirements, thereby obtaining transmission signals of different signal levels, and realizing the selection of different transmission paths under different signal level requirements.

[0103] In related technologies, filtering primarily eliminates spurious or harmonic sidebands of the main wave. Sideband spurs are primarily influenced by the transmitter's output signal, while spurious signals are primarily affected by nonlinear effects such as amplifiers in the transmission path. For signals that require filtering, this requires adding additional loss to the transmission path. As shown in Figures 2 and 3, the passband losses of typical 2.4 / 5G filtering are approximately 0.9dB at 2.4GHz (Figure 2), and 0.7dB at 5GHz (Figure 3). In related RF devices, regardless of power level or signaling mode, signals must be filtered by the corresponding filters. For some communication scenarios where filtering is not necessary, additional filtering results in excessive loss.

[0104] In this embodiment, the first selection circuit 300 in the RF device selects and switches the target transmission path between the RF transceivers 20. This allows either the first transmission path 100 or the second transmission path 200 to perform transmission processing on the first communication signal to be transmitted under different communication requirements, thereby obtaining transmission signals of different signal levels and selecting different transmission paths under different signal level requirements. Compared to related technologies, this can reduce overall channel loss while meeting the corresponding communication requirements.

[0105] In one embodiment, the first selection circuit 300 is used to select and connect the target transmission path and the RF transceiver 20 according to the power mode, and the amplification power of the power mode corresponding to the second transmission path 200 is less than the amplification power of the power mode corresponding to the first transmission path 100.

[0106] The amplification power corresponding to the power mode of the first transmit path 100 is greater than the amplification power corresponding to the power mode of the second transmit path 200. The first transmit path 100 has a higher power mode level than the second transmit path 200. Through amplification and filtering, a higher-gain first communication signal can be obtained, meeting high-power communication requirements. The second transmit path 200 has a lower power mode level than the first transmit path 100. Its inherent linearity is sufficient, and its harmonic margin is sufficient to eliminate the need for filtering. No additional filtering is required, thus saving unnecessary losses and meeting high-signal-strength communication requirements. The first selection circuit 300 selectively connects the target transmit path to the RF transceiver 20 based on the power mode requirement, selecting the transmit path that matches the target power mode requirement, thereby reducing channel loss while meeting the corresponding mode requirement.

[0107] Optionally, the first transmitting path 100 can correspond to a high / medium power mode (High Power Mode / Midle Power Mode, HPM / MPM) channel to realize high / medium power amplification and filtering processing functions of the first communication signal, for example, it can meet communication requirements above 15dBm; the second transmitting path 200 can correspond to a low power mode (Low Power Mode, LPM) channel to realize low power amplification processing functions of the first communication signal, for example, it can meet communication requirements of 0-15dBm.

[0108] In one embodiment, the first gating circuit 300 is used to selectively connect the target transmission path to the RF transceiver 20 according to the scenario type, and the first transmission path 100 and the second transmission path 200 correspond to the same power mode.

[0109] The power mode of the first transmit path 100 is identical to the power mode of the second transmit path 200. Therefore, the first transmit path 100 and the second transmit path 200 can amplify signals at the same amplification power. The first transmit path 100 incorporates additional signal filtering to achieve high interference suppression, making it suitable for communication scenarios with high levels of signal interference. The second transmit path 200 does not require additional signal filtering and is suitable for scenarios where front-end filtering losses can be eliminated to improve channel performance. The first selection circuit 300 selectively connects the target transmit path to the RF transceiver 20 based on the communication scenario, selecting a transmit path that matches the target communication scenario and reducing channel loss while meeting the corresponding communication scenario. Optionally, the first transmit path 100 and the second transmit path 200 can correspond to HPM / MPM mode channels, respectively, to implement high / medium power transmit processing for the first communication signal.

[0110] It can be understood that in other embodiments, the first selection circuit 300 can selectively conduct the connection between the target transmission path and the RF transceiver 20 according to the power mode requirements and the communication scenario type, thereby selecting a transmission path that matches the target power mode requirements and meets the target communication scenario requirements. The relevant selection method can refer to the above two embodiments at the same time and will not be repeated here.

[0111] In one embodiment, as shown in FIG. 4 , the first transmitting path 100 includes a first power amplifier circuit 110 and a filter circuit 120 ; the second transmitting path 200 includes a second power amplifier circuit 210 .

[0112] The first power amplifier circuit 110 is connected to a second end of the first selection circuit 300, and is used to perform power amplification processing on the received first communication signal; the filter circuit 120 is connected to the power amplifier circuit, and the filter circuit 120 can be conductively connected to the antenna port, and is used to filter the first communication signal after power amplification processing; the second power amplifier circuit 210 is connected to a second end of the first selection circuit 300, and is used to perform power amplification processing on the received first communication signal.

[0113] The first power amplifier circuit 110 and the second power amplifier circuit 210 may each include a power amplifier (PA) for performing power amplification processing on the received signal. Optionally, when the first transmit path 100 and the second transmit path 200 are different power mode channels, for example, the first transmit path 100 is an HPM / MPM mode channel and the second transmit path 200 is an LPM mode channel, the first power amplifier circuit 110 and the second power amplifier circuit 210 may correspond to an HPM / MPM PA and an LPM PA, respectively. Optionally, when the first transmit path 100 and the second transmit path 200 are the same power mode channels, for example, the first transmit path 100 and the second transmit path 200 may be HPM / MPM mode channels, the first power amplifier circuit 110 and the second power amplifier circuit 210 may respectively correspond to an HPM / MPM PA.

[0114] Among them, the filtering circuit 120 may include a surface acoustic wave (SAW) filter that only allows communication signals in a preset frequency band to pass through to eliminate spurious or harmonic sidebands of the main wave. The filter may be a bandpass filter, a low-pass filter, etc. It should be noted that in the embodiment of the present application, the type of filter in the filtering circuit 120 is not further limited, and a suitable filter can be selected according to the frequency band of the communication signal to be filtered.

[0115] In this embodiment, the first transmit path 100 implements signal power amplification and filtering functions to support transmit processing through a first power amplifier circuit 110 and a filter circuit 120. The second transmit path 200 implements signal power amplification and filtering functions to support transmit processing through a second power amplifier circuit 210. Thus, the first transmit path 100 and the second transmit path 200 can obtain signals of different levels through different transmit processing processes, thereby reducing channel loss based on matching different power modes and / or different communication scenarios.

[0116] In one embodiment, as shown in FIG5 , the radio frequency device further includes: a second gating circuit 400 .

[0117] The first end of the second gating circuit 400 is connected to the antenna port, and the multiple second ends of the second gating circuit 400 are respectively connected to the filter circuit 120 and the second power amplifier circuit 210. The second gating circuit 400 is used to selectively connect the target transmission path to the antenna. Thus, the first gating circuit 300 and the second gating circuit 400 can jointly select and connect the target transmission path to the RF transceiver and the antenna. Optionally, the second gating circuit 400 can be a single-pole multi-throw switch or a multi-pole multi-throw switch.

[0118] It can be understood that the second gating circuit 400 works together with the first gating circuit 300. Therefore, the selection basis for the conduction of the second gating circuit 400 may be the same as that of the first gating circuit 300. For example, the connection between the target transmission path and the antenna can be selectively turned on according to the power mode, the connection between the target transmission path and the antenna can be selectively turned on according to the scenario type, and the connection between the target transmission path and the antenna can also be selectively turned on according to the power mode requirements and the communication scenario type. For related descriptions, please refer to the above embodiments and will not be repeated here.

[0119] In one embodiment, please continue to refer to FIG. 5 , the radio frequency device further includes: a first bypass 500 .

[0120] The first bypass 500 is connected to a second end of the first gating module 300 and a second end of the second gating module 400 respectively, for transmitting the first communication signal; wherein the target transmission path includes one of the first transmission path 100, the second transmission path 200 and the first bypass 500.

[0121] Among them, the first bypass 500 can be understood as a transmission channel with no loss or loss approaching zero. The first bypass 500 supports the transmission of signals and does not require amplification and filtering of the signals, which can further save excess losses and meet the ultra-low loss communication requirements. The amplification power of the power mode corresponding to the second transmission path 200 is greater than the amplification power of the power mode corresponding to the first bypass 500.

[0122] When each of the aforementioned gating circuits selects and connects the target transmit path to the RF transceiver 20 and the antenna, respectively, based on the power mode, the first bypass path 500 has the lowest power mode level and relatively lowest loss relative to the first transmit path 100 and the second transmit path 200, thereby meeting the communication requirements of lossless or near-lossless transmission. Furthermore, the first bypass path 500 can be understood as an ultra-low power mode, enabling ultra-low power amplification and processing of the first communication signal, for example, meeting communication requirements below 0 dBm.

[0123] Among them, when the above-mentioned selection circuits select the connection between the target transmission path and the RF transceiver 20 and the antenna respectively according to the scenario type, the first bypass 500 has the lowest power mode level and the lowest loss relative to the first transmission path 100 and the second transmission path 200, which can meet the communication scenario of lossless transmission or near lossless transmission.

[0124] In this embodiment, the first gating circuit 300 is respectively connected to the RF transceiver 20, the first transmission path 100, the second transmission path 200, and the first bypass 500. Thus, through the gating function of the first gating circuit 300, the RF transceiver 20 can be switchably connected to the target transmission path, thereby realizing the transmission path selection switching function. The second gating circuit 400 is respectively connected to the antenna, the first transmission path 100, the second transmission path 200, and the first bypass 500. Thus, through the gating function of the second gating circuit 400, the antenna can be switchably connected to the target transmission path, thereby realizing the transmission path selection switching function.

[0125] Through the combined action of the first gating circuit 300 and the second gating circuit 400, a target transmission path between the RF transceiver 20 and the antenna can be selectively conducted, so that any one of the first transmission path 100, the second transmission path 200, and the first bypass path 500 can perform transmission processing on the first communication signal to be transmitted under different communication requirements, thereby obtaining transmission signals of different signal levels, thereby realizing the selection of different transmission paths under different signal level requirements.

[0126] In one embodiment, as shown in FIG6 , the amplified power of the first power amplifier circuit 110 is greater than the amplified power of the second power amplifier circuit 210. The first transmit path 100 can correspond to a higher power mode, and the second transmit path 200 can correspond to a lower power mode relative to the first transmit path 100. The RF device may further include a third gating circuit 600.

[0127] The two first ends of the third gating circuit 600 are respectively connected to the filter circuit 120 and the other second end of the second gating circuit 400, and a second end of the third gating circuit 600 is connected to the first power amplifier circuit 110. The third gating circuit 600 is used to selectively conduct the connection between the first power amplifier circuit 110 and the filter circuit 120 to form the first transmission path 100, or the connection between the first power amplifier circuit 110 and the second gating circuit 400 to form the third transmission path; wherein, the target transmission path includes one of the first transmission path 100, the second transmission path 200, and the third transmission path, and the target transmission path may also include one of the first transmission path 100, the second transmission path 200, the third transmission path and the first bypass path 500; the third transmission path and the first transmission path 100 respectively power amplify the first communication signal under different scenario types.

[0128] The third selection circuit 600 is respectively connected to the filter circuit 120, the second selection circuit 400, and the first power amplifier circuit 110. The first power amplifier circuit 110 can be selectively connected to the filter circuit 120 to form a first transmission path 100 with amplification and filtering functions, thereby amplifying and filtering the signal. The first power amplifier circuit 110 can also be selectively connected directly to the second selection circuit 400 to form a third transmission path that does not require filtering, thereby reducing the loss of the third transmission path. The first transmission path 100 and the third transmission path each include the first power amplifier circuit 110, and the third transmission path omits the filter circuit 120 to reduce loss and improve channel performance. Therefore, the two transmission paths can correspond to transmission paths of the same power mode level and are suitable for communication scenarios with different communication performance requirements.

[0129] Furthermore, the third gating circuit 600 combines the gating functions of the first gating circuit 300 and the second gating circuit 400, thereby realizing the selection function of different channels under different power modes, and can select one of the first transmission path 100, the second transmission path 200 and the first bypass path 500, or select one of the first transmission path 100 and the second transmission path 200 to match the corresponding power mode requirements; at the same time, it can also realize the selection function of different channels under the same power mode, and can select one of the first transmission path 100 and the third transmission path to match the corresponding communication scenario requirements in the high power mode.

[0130] Therefore, the radio frequency device provided in this embodiment can improve the flexibility of channel selection on the basis of reducing the overall loss of the radio frequency device, so as to meet more communication requirements and improve communication performance.

[0131] In one embodiment, as shown in FIG7 , the RF device is further configured with a receiving port for connecting to the RF transceiver 20 , and the RF transceiver 20 is further configured to transform and process the received communication signal; the RF device further includes: a first receiving circuit 700 .

[0132] The first receiving circuit 700 is respectively connected to the receiving port and the other second end of the third gating circuit 600, and is used to receive and process the first communication signal received by the antenna; wherein, the third gating circuit 600 is also used to select the connection between the conductive filtering circuit 120 and the first receiving circuit 700, or the connection between the second gating circuit 400 and the first receiving circuit 700; the second gating circuit 400 is also used to selectively conduct the connection between the third gating circuit 600 and the antenna.

[0133] Among them, the antenna port is also used to receive the communication signal received by the antenna. The RF device can receive and process the communication signal input by the antenna port to output it to the corresponding receiving port, and then output it to the RF transceiver 20 through the receiving port to realize the reception control of the communication signal.

[0134] Among them, the two first ends of the third gating circuit 600 are respectively connected to the filter circuit 120 and the second gating circuit 400, and the two second ends of the third gating circuit 600 are respectively connected to the first power amplifier circuit 110 and the first receiving circuit 700. The third gating circuit 600 can selectively conduct the connection between the first power amplifier circuit 110 and any one of the filter circuit 120 and the second gating circuit 400, and can also selectively conduct the connection between the first receiving circuit 700 and any one of the filter circuit 120 and the second gating circuit 400. Therefore, the third gating circuit 600 can select the transmitting and receiving channels, and can also select the target transmitting path in the transmitting state, and select the target receiving channel in the receiving state, thereby realizing the transmitting and receiving state switching function and the channel switching function.

[0135] Among them, the filter circuit 120 can be connected to the first power amplifier circuit 110 through the third selection circuit 600 to form the first transmitting path 100, and can also be connected to the first receiving circuit 700 to realize the receiving filtering function in combination with the first receiving circuit 700. Therefore, the filter circuit 120 serves as a functional device of the transmitting path and is reused as a functional device of the receiving channel to realize the filtering processing function on different channels, thereby improving the reuse rate of the filter circuit 120, reducing the number of devices, and improving the integration, thereby reducing the cost and the occupied area of ​​​​RF devices.

[0136] Therefore, the radio frequency device provided in this embodiment can realize the transmitting and receiving state switching function and the channel switching function, and also has a high degree of integration, low cost and occupied area.

[0137] In one embodiment, as shown in FIG8 , the first receiving circuit 700 includes a low noise amplifier unit 710 and a second bypass 720 .

[0139] Among them, the low-noise amplification unit 710 can form a receiving channel of the radio frequency device together with the filtering circuit 120, and perform low-noise amplification and filtering processing functions on the first communication signal to realize the reception and processing of the first communication signal by the radio frequency device, amplify the effective signal without increasing the noise, thereby improving the signal-to-noise ratio of the received first communication signal, and then improving the signal processing quality of the radio frequency device, which can meet the communication requirements of a higher signal-to-noise ratio; the second bypass 720 forms another receiving channel of the radio frequency device, which can be understood as a transmission channel with no loss or loss approaching zero. The second bypass 720 supports the transmission of the signal and does not require amplification and filtering of the signal, which can further save excess loss and meet the communication requirements of ultra-low loss. Optionally, the low-noise amplification unit 710 includes a low-noise amplifier to achieve low-noise amplification processing of the signal.

[0140] The third gating circuit 600 is also respectively connected to the low-noise amplifier, the second bypass 720, the filter circuit 120, and the second gating circuit 400, and can selectively conduct the connection between the filter circuit 120 and the low-noise amplification unit 710, or the connection between the second gating circuit 400 and the second bypass 720, thereby realizing the selective conduction function of the two receiving channels of the radio frequency device for receiving the first communication signal.

[0141] Therefore, the radio frequency device provided in this embodiment can also support the selection and switching function of the receiving channel, further improving the flexibility of the channel selection of the radio frequency device, matching different communication requirements, and further reducing the loss.

[0142] In one embodiment, the RF device is further configured with a receiving port for connecting to the RF transceiver 20, and the RF transceiver 20 is further configured to transform and process the received communication signal. As shown in Figures 9 and 10, the RF device also includes: a second receiving circuit 800. The second receiving circuit 800 is respectively connected to the receiving port and a second end of the second selection circuit 400, and is configured to receive and process the first communication signal received by the antenna, so that the RF device supports reception of the first communication signal.

[0143] Optionally, the second receiving circuit 800 may include a receiving unit and a fourth bypass channel, the receiving unit being connected to the receiving port and the second gating circuit 400 respectively, and the fourth bypass channel being connected to the receiving port and the second gating circuit 400 respectively. The receiving unit forms a receiving channel of the RF device, and performs low-noise amplification and filtering processing functions on the first communication signal to realize the reception and processing of the first communication signal by the RF device, amplifying the effective signal without increasing the noise, thereby improving the signal-to-noise ratio of the received first communication signal, and further improving the signal processing quality of the RF device, which can meet the communication requirements of a higher signal-to-noise ratio; the fourth bypass channel forms another receiving channel of the RF device, which can be understood as a transmission channel with no loss or loss approaching zero. The fourth bypass channel supports the transmission of the signal without the need for amplification and filtering of the signal, which can further save excess loss and meet the communication requirements of ultra-low loss. Optionally, the receiving unit may include a low-noise amplifier and a filter, and the filter is connected to the low-noise amplifier and the second gating circuit 400 respectively, so that the receiving unit realizes the filtering and amplification functions.

[0144] Therefore, the radio frequency device provided in this embodiment can also support different receiving and processing functions, further improving the flexibility of the radio frequency device receiving and processing selection, matching different communication requirements, and further reducing losses.

[0145] In one embodiment, the RF device is further configured with a coupling port for connecting to the RF transceiver 20 , as shown in FIG. 11 to FIG. 13 . The RF device further includes: a coupling circuit 900 .

[0146] The input end of the coupling circuit 900 is connected to the first end of the second selection circuit 400, the output end of the coupling circuit 900 is connected to the antenna port, and the coupling end of the coupling circuit 900 is connected to the coupling port. The coupling circuit 900 is used to couple the signal on the connected path to detect power information.

[0147] The coupling circuit 900 is provided in the path between the second selection circuit 400 and the antenna, and is used to couple the communication signal in the path, detect the power information of the communication signal to generate a coupled signal, and output the coupled signal to the RF transceiver 20 via the coupled output terminal. Specifically, the coupling circuit 900 may include a coupler, and the coupled signal may include a forward coupled signal and a reverse coupled signal. Based on the forward coupled signal, the RF transceiver 20 may detect the forward power information of the communication signal; based on the reverse coupled signal, the RF transceiver 20 may correspondingly detect the reverse power information of the communication signal.

[0148] In one embodiment, in any one of the above embodiments or a combination of multiple embodiments, the first communication signal includes one of a 2.4G WIFI signal and a 5G WIFI signal. Thus, the radio frequency device can support one of the 2.4G WIFI signal and the 5G WIFI signal, and the radio frequency device can be a 2.4G WIFI FEM or a 5G WIFI FEM. The frequency band ranges of the two signals are shown in Table 1 below:

[0149] Table 1 Frequency ranges of 2.4G WIFI and 5G WIFI

[0150] In one embodiment, the first transmitting path 100 is further used to amplify and filter the second communication signal, the second transmitting path 200 is further used to amplify the second communication signal, and the first bypass 500 is further used to transmit the second communication signal; wherein the frequency band of the second communication signal and the frequency band of the first communication signal are respectively in the same frequency range of different standards.

[0151] The second communication signal and the first communication signal being in the same frequency range can be understood as the second communication signal and the first communication signal having the same or similar frequencies. If they are similar, they can be in adjacent frequency bands or cross-frequency bands. Because the second communication signal and the first communication signal are in different formats and have the same or similar frequencies, each transmission path can support the transmission processing of the second communication signal in addition to supporting the transmission processing of the first communication signal. This allows the RF device to support the transmission of both communication signals, improving the applicable scenarios of the RF device.

[0153] The third bypass 1000 is connected to the transmission port and a second end of the second selection circuit 400, respectively, and is used to receive the second communication signal when connected to the antenna port. The second selection circuit 400 can also selectively conduct the connection between the third bypass 1000 and the antenna, so that the RF device supports the reception of the second communication signal through the third bypass 1000. The third bypass 1000 can be understood as a transmission channel with no loss or loss close to zero. The third bypass 1000 supports the transmission of signals without the need for signal amplification and filtering, which can further save excess loss and meet ultra-low loss communication requirements.

The first communication signal includes a 2.4G WIFI signal, and the second communication signal includes a 2.4G BT signal. Therefore, the RF device may be a 2.4G WIFI FEM that supports both 2.4G WIFI and 2.4G BT signals. The frequency bands of the two signals are shown in Table 2 below:
