[0029] like Figure 1 As shown, an embodiment of the present application provides a communication device, including: a radio frequency transceiver 10, a first radio frequency device 20 and a second radio frequency device 30.
[0030] RF transceiver 10; a first RF device 20, configured with multiple transmit input ports connected to the RF transceiver 10 (only one connection between the first RF device 20 and the RF transceiver 10 is shown in the figure, and it can be understood that the connection path in the figure is only for illustration and not for limitation), a first antenna port and a second antenna port (only one connection between the first RF device 20 and the second RF device 30 is shown in the figure), used to support the transmission processing of the UHF signal and the non-UHF signal to be transmitted, and transmit the UHF signal through the first antenna port, and transmit the non-UHF signal through the second antenna port; the second RF device 30, configured with multiple first receive output ports connected to the RF transceiver 10, a transmission port connected to the first antenna port, and multiple antenna ports correspondingly connected to multiple antennas (four antennas are used as an example in the figure, namely ANT1, ANT2, ANT3 and ANT4), used to switchably connect the first RF device 20 to any one of the multiple antennas, so as to transmit the UHF signal through any antenna, and support multi-channel reception of the UHF signal through the multiple antennas.
[0031] The RF transceiver 10 is used to support the output of UHF signals and non-UHF signals to be transmitted, so as to be transmitted by the first RF device 20 for processing; and is also used to support the reception of UHF signals after receiving and processing by the second RF device 30, and non-UHF signals after receiving and processing by other receiving modules. Further, the RF transceiver 10 can be used to implement the frequency conversion processing between the aforementioned RF signals and the baseband signals, or / and, to implement the frequency conversion processing of signals in different frequency bands, etc.
[0032] Among them, the first RF device 20 can be understood as a packaging structure, which is configured with multiple transmit input ports, a first antenna port, and a second antenna port connected to the RF transceiver 10. The transmit input port, the first antenna port, and the second antenna port can be understood as RF pin terminals of the first RF device 20, which are used to connect to internal and external devices. In one embodiment, the first RF device 20 in the embodiment of the present application may include four or more transmit input ports, and may include one or more first antenna ports, and one or more second antenna ports.
[0033] The transmit input port is used to transmit UHF signals and non-UHF signals from the RF transceiver 10; the first antenna port is used to transmit UHF signals, and the second antenna port is used to transmit non-UHF signals. The first RF device 20 is used to perform transmission processing on the UHF signals and non-UHF signals input into the transmit input port, and then transmit them through the first antenna port and the second antenna port accordingly.
[0034] Transmitting processing may be, for example, power amplification processing, and non-UHF signals include at least one of low-frequency signals, intermediate-frequency signals, and high-frequency signals. It can be understood that the number of the aforementioned ports can be adjusted according to the actual frequency band requirements. Therefore, the first RF device 20 can be understood as a multimode multiband power amplifier (MMPA) to support power amplification processing of at least one of low-frequency signals, intermediate-frequency signals, and high-frequency signals and UHF signals. In this embodiment, only one first RF device 20 is required to realize the transmission processing of RF signals of various frequency bands including UHF signals and non-UHF signals. Compared with the related technology that requires multiple discrete transmitting devices to realize the corresponding functions, it can greatly reduce the occupied area of the circuit board, improve the integration of the device, and reduce the cost.
[0035] Among them, the low-frequency signal may include a radio frequency signal of a low-frequency band, and may also include radio frequency signals of multiple low-frequency bands, and the radio frequency signal may include at least one of a 4G LTE low-frequency signal and a 5G NR low-frequency signal; similarly, the intermediate frequency signal, the high frequency signal and the ultra-high frequency signal may each include a signal of a corresponding frequency band, and may also include radio frequency signals of multiple corresponding frequency bands, and the radio frequency signal may include at least one of a 4G LTE signal and a 5G NR signal. Among them, the frequency band division of low-frequency signals, intermediate frequency signals, high frequency signals and ultra-high frequency signals can refer to the following table (it should be noted that the frequency band used by 4G is used in the 5G network, and only the identification before the serial number is changed. Therefore, the modules and units applicable to processing 4G frequency band signals in the following examples are also applicable to processing signals of the corresponding frequency bands of 5G).
[0036] Among them, the second RF device 30 can be understood as a packaging structure, which is configured with multiple first receiving output ports connected to the RF transceiver 10, a transmission port connected to the first antenna port, and multiple antenna ports corresponding to multiple antennas. The first receiving output port, the transmission port, and the antenna port can be understood as the RF pin terminals of the second RF device 30, which are used to connect to internal and external devices. In one embodiment, the second RF device 30 in the embodiment of the present application may include one or more transmission ports, may include one or more first receiving output ports, and two or more antenna ports.
[0037] The transmission port is used to transmit the UHF signal after the transmission processing from the first RF device 20; the antenna port is used to transmit the UHF signal, and the first receiving output port is used to transmit the UHF signal after the reception processing by the second RF device 30. The second RF device 30 is used to switchably connect the first antenna port of the first RF device 20 to any one of the multiple antennas to transmit the UHF signal from the first RF device 20 through the any one of the antennas; and the multiple antennas connected support multi-channel reception of the UHF signal, thereby realizing one-way transmission and multi-channel reception processing of the UHF signal. Furthermore, the first RF device 20 can be switchably connected to any one of the multiple antennas, and the first RF device 20 can also support the round-robin function of the UHF signal.
[0038] The above-mentioned receiving process can be, for example, a low noise amplification process. It can be understood that the number of the above-mentioned ports can be adjusted according to actual needs. Therefore, the second radio frequency device 30 can be understood as a low noise amplifier front-end module (Low Noise AmPlifier-Front-End Modules, LFEM) with a function of transmitting a signal to be transmitted, so as to support the transmission and low noise amplification of ultra-high frequency signals. In this embodiment, only one second radio frequency device 30 is required to realize the transmission of the ultra-high frequency signal to be transmitted, and to realize the switching and gating function of multiple antennas, and can also realize multi-channel reception of ultra-high frequency signals. Compared with the related technology that requires multiple discrete receiving devices, antenna switching switches, etc. to realize the corresponding functions (for example, when it is necessary to support four-way reception of ultra-high frequency signals, four discrete radio frequency receiving devices and two antenna switching switches are required), the occupied area of the circuit board can be greatly reduced, the integration of the device can be improved, and the cost can be reduced; at the same time, the wiring between the discrete receiving devices, transmitting devices and antenna switching switches can be greatly reduced, and the complexity of the internal wiring of the communication equipment can be greatly reduced.
[0039] The communication device provided in this embodiment can realize the transmission and processing of radio frequency signals of various frequency bands including ultra-high frequency signals, non-ultra-high frequency signals, etc., realize the switching and gating function of multiple transmitting antennas, and can also realize multi-channel reception of ultra-high frequency signals through the radio frequency transceiver 10, the first radio frequency device 20 and the second radio frequency device 30. Compared with the related technology that needs to realize the corresponding functions through multiple discrete transmitting devices, receiving devices and antenna switching switches, it can greatly reduce the occupied area of the circuit board, improve the integration of the device, and reduce the cost; at the same time, it can save the wiring between the discrete receiving devices, the transmitting devices and the antenna switching switch, etc., greatly reduce the number of wiring, and greatly reduce the complexity of the internal wiring of the communication equipment.
[0040] In one embodiment, if Figure 2As shown, the first RF device 20 includes: a first RF module 210 and a second RF module 220 (the number of ports in the figure is for illustration only and is not limited; the transmit input port of the first RF device 20 is RFIN1, RFIN2, etc. in the figure, the first antenna port is RFOUT1, RFOUT2, etc. in the figure, and the second antenna port is LMHB in the figure).
[0041] The first RF module 210 is respectively connected to the transmit input port and multiple first antenna ports, and is used for transmitting the ultra-high frequency signal to be transmitted, and can switchably select to transmit the processed ultra-high frequency signal through any first antenna port; the second RF module 220 is respectively connected to another part of the transmit input port and the second antenna port of the first RF device 20, and is used to support the transmission processing of the non-ultra-high frequency signal to be transmitted.
[0042] Among them, the first RF module 210 can be connected to the RF transceiver 10 and the second RF device 30 respectively through the transmission input port and the first antenna port, thereby, it can receive the ultra-high frequency signal to be transmitted from the RF transceiver 10, and perform transmission processing on the ultra-high frequency signal, and can selectively switch the first antenna port used to transmit the ultra-high frequency signal, and connect the selected first antenna port to the second RF device 30 by switching, so as to transmit the ultra-high frequency signal to the antenna through the second RF device 30 for transmission.
[0043] Among them, the second RF module 220 can be connected to the RF transceiver 10 and other RF processing circuits through the transmission input port and the second antenna port respectively, thereby receiving the non-ultra-high frequency signal to be transmitted from the RF transceiver 10, and performing transmission processing on the non-ultra-high frequency signal, and transmitting the non-ultra-high frequency signal to the antenna through the second antenna port and other RF processing circuits for transmission.
[0044] The first RF module 210 and the second RF module 220 integrate the first RF device 20, so that the first RF device 20 can simultaneously transmit and process UHF signals and non-UHF signals, which can greatly reduce the occupied area of the circuit board, improve the integration of the device, and reduce costs.
[0045] In one embodiment, when the first RF module 210 supports the transmission of UHF signals, Figure 3 As shown, the first RF module 210 includes: an ultra-high frequency transmitting unit 211 and a first gating unit 212 .
[0046] The ultra-high frequency transmitting unit 211 is connected to the transmitting input port and is used to support the receiving and transmitting processing of the ultra-high frequency signal to be transmitted; the first gating unit 212, a first end of the first gating unit 212 is connected to the ultra-high frequency transmitting unit 211, and multiple second ends of the first gating unit 212 are respectively connected to multiple first antenna ports, and the second gating unit is used to switchably select and conduct the connection between the ultra-high frequency transmitting unit 211 and any first antenna port.
[0047] Among them, the UHF transmitting unit 211 is connected to the RF transceiver 10 through the transmitting input port to receive the UHF signal to be transmitted, and is connected to multiple first antenna ports through the first gating unit 212. The first gating unit 212 can switchably select the connection between the UHF transmitting unit 211 and any first antenna port. Thus, the transmitting input port can be respectively connected to multiple first antenna ports through the second gating unit to form a multi-channel transmitting path, and the multi-channel transmitting paths can be arbitrarily switched through the first gating unit 212, thereby improving the flexibility of channel selection of the first RF module 210.
[0048] Optionally, the UHF transmitting unit 211 may include a power amplifier, and further, may include a filter, so that the UHF transmitting unit 211 can realize power amplification and filtering processing of the UHF signal. Optionally, the first gating unit 212 may include a multi-channel selection switch, and the number of ports of the multi-channel selection switch may be adjusted and set according to actual needs. It can be understood that the first RF module 210 may also add relevant devices based on the needs of other additional functions in practice. For example, based on the monitoring needs of the transmission function of the UHF signal, a corresponding coupling unit is set on the path between the UHF transmitting unit 211 and the first gating unit 212 to obtain the coupling signal when the UHF transmitting unit 211 transmits the UHF signal. The coupling signal is output to the RF transceiver 10 for the RF transceiver 10 to measure the forward coupling power and reverse coupling power of the low-frequency signal. The coupling unit may include a coupler, or a switching switch may be set according to needs to switch the output end of the coupler to connect the coupling output port (such as CPLOUT1 in the figure) and the coupling input port (such as CPLIN1 in the figure).
[0049] Optionally, multiple first antenna ports can be respectively connected to different antennas through the second RF device 30 or other devices. Thus, based on the switching of multiple first antenna ports, the first antenna port corresponding to a more efficient antenna can be selected to support the transmission of ultra-high frequency signals, thereby improving the RF performance of the communication device.
[0050] In one embodiment, if Figure 4 As shown, in Figure 3Based on the embodiment, the number of second RF devices 30 is two, each second RF device 30 is connected to multiple antennas, and each second RF device 30 is connected to the UHF transmitting unit 211 through a first antenna port; wherein the first selection unit 212 is used to switchably select the connection between the UHF transmitting unit 211 and any second RF device 30; and any second RF device 30 is used to switchably select the connection between the UHF transmitting unit 211 and any antenna among the multiple antennas.
[0051] On the one hand, the first selection unit 212 is connected to the two second RF devices 30 through the two first antenna ports respectively, and can switchably select and conduct the connection between the UHF transmitting unit 211 and any second RF device 30, so that the UHF transmitting unit 211 transmits an UHF signal through any second RF device 30; on the other hand, each second RF device 30 is connected to multiple antennas, and any second RF device 30 can also switchably conduct the connection between the UHF transmitting unit 211 and any antenna of the multiple antennas, thereby improving the flexibility of antenna switching selection on the basis of improving the flexibility of RF device selection, and improving RF performance; at the same time, compared with related technologies that require multiple discrete receiving devices, antenna switching switches, etc. to implement corresponding functions (for example, when it is necessary to support four-way reception of UHF signals, four discrete RF receiving devices and two antenna switching switches are required), the occupied area of the circuit board can be reduced, the integration of the device can be improved, and the cost and complexity of the internal wiring of the communication equipment can be reduced.
[0052] It can be understood that in other embodiments, the number of second RF devices 30 can be more than two, each second RF device 30 is connected to multiple antennas, and each second RF device 30 is connected to the UHF transmitting unit 211 through a first antenna port. Thus, the first selection unit 212 is used to switchably select the connection between the UHF transmitting unit 211 and a larger number of second RF devices 30, thereby realizing the switching connection of more antennas.
[0053] It can be understood that the above embodiment only shows an embodiment of two or more second RF devices 30 on the basis that the first RF module 210 only supports the transmission function. However, the embodiment of two or more second RF devices 30 can also be applied to the embodiment in which the first RF module 210 supports transmission and at least one channel reception in the following text, and the embodiment of the present application does not further limit this.
[0054] In one embodiment, the second RF device 30 is also used to transmit an ultra-high frequency signal from any antenna to the first RF device 20; Figure 4As shown, the first RF device 20 is also configured with a second receiving output port connected to the RF transceiver 10, and the first RF module 210 is also used to support at least one channel reception of the UHF signal through at least one first antenna port. It can be understood that the transmit input port and the second receive output port are respectively connected to different first antenna ports, or respectively connected to the same first antenna port. When the first RF device 20 supports one-channel reception, by setting a transmit input port and a second receive output port to be respectively connected to the same first antenna port, it is beneficial to realize port multiplexing and improve port utilization.
[0055] In this embodiment, the first RF device 20, in addition to supporting the transmission processing of UHF signals and non-UHF signals, can also simultaneously support at least one receiving processing of UHF signals, which can further expand the transceiver processing function of the first RF device 20 and improve the integration of the first RF device 20, thereby further reducing the complexity of the internal wiring of the communication device.
[0056] In one embodiment, when the first RF module 210 supports transmission and one-channel receiving functions, please continue to refer to Figure 4 The first radio frequency module 210 includes: an ultra-high frequency transceiver unit 213 and a second gating unit 214 .
[0057] The ultra-high frequency transceiver unit 213 is respectively connected to the transmission input port and the second receiving output port (such as OUT1 in the figure), and is used to support the transceiver processing of the ultra-high frequency signal; the second gating unit 214, a first end of the second gating unit 214 is connected to the ultra-high frequency transceiver unit 213, and multiple second ends of the second gating unit 214 are respectively connected to multiple first antenna ports. The second gating unit 214 is used to switchably select and conduct the connection between the ultra-high frequency transceiver unit 213 and any first antenna port.
[0058] Among them, the ultra-high frequency transceiver unit 213 is connected to the RF transceiver 10 through the transmitting input port and the second receiving output port respectively, and is connected to multiple first antenna ports through the second gating unit 214. The second gating unit 214 can switchably select to connect the ultra-high frequency transceiver unit 213 and any first antenna port. Thus, the transmitting input port and the second receiving output port can be connected to the same first antenna port through the second gating unit 214 to form a transmitting path and a receiving path respectively, and the transmitting path and the receiving path can be arbitrarily switched among multiple first antenna ports through the second gating unit 214, thereby improving the flexibility of channel selection of the first RF module 210.
[0059] Optionally, the UHF transceiver unit 213 may include a power amplifier and a low noise amplifier, and further, may include a filter, so that the UHF transceiver unit 213 can realize power amplification processing, low noise amplification processing and filtering processing of the UHF signal. Optionally, the second selection unit 214 may include a multi-channel selection switch, and the number of ports of the multi-channel selection switch can be adjusted and set according to actual needs. It can be understood that the first RF module 210 can also add relevant devices based on the needs of other additional functions in practice. For example, based on the monitoring needs of the transmission function of the UHF signal, a corresponding coupling unit is set on the path between the UHF transceiver unit 213 and the second selection unit 214 to obtain the coupling signal when the UHF transceiver unit 213 transmits the UHF signal. The relevant introduction of the coupling unit can refer to the above embodiment and will not be repeated here.
[0060] Optionally, multiple first antenna ports can be respectively connected to different antennas through the second RF device 30 or other devices. Thus, based on the switching of multiple first antenna ports, the first antenna port corresponding to a more efficient antenna can be selected to support the transmission and reception of ultra-high frequency signals, thereby improving the RF performance of the communication device.
[0061] In one embodiment, when the first RF module 210 also supports receiving another channel of the UHF signal; Figure 5 As shown, the first RF module 210 further includes: an ultra-high frequency receiving unit 215 .
[0062] The UHF receiving unit 215 is connected to the second receiving output port and the other first end of the second gating unit 214, respectively, to support receiving and processing of the received UHF signal; wherein the second gating unit 214 is also used to select and conduct the connection between the UHF receiving unit 215 and a first antenna port. Optionally, the UHF receiving unit 215 may include a low noise amplifier to perform low noise amplification processing on the received UHF signal.
[0063] On the one hand, the first RF module 210 can form one transmission path and two reception paths through the UHF transceiver unit 213, the UHF receiving unit 215, and the second selection unit 214, thereby further improving the integration of the first RF device 20 on the basis of expanding the number of reception paths and improving the reception performance; on the other hand, the transmission path and the transceiver path formed by one of the reception paths can be switchably connected to any first antenna port to achieve multi-port switching, and the other reception path can also be selectively connected to one of the first antenna ports, thereby further improving the flexibility of channel selection of the first RF device 20.
[0064] In one embodiment, in any of the above embodiments, Figure 6-Figure 8As shown, the second RF module 220 may include a low frequency transmitting unit, an intermediate frequency transmitting unit and a high frequency transmitting unit, and the low frequency transmitting unit, the intermediate frequency transmitting unit and the high frequency transmitting unit are respectively used for transmitting low frequency signals, intermediate frequency signals and high frequency signals. Optionally, the transmitting process may be a power amplification process, and each transmitting unit may include a power amplifier; further optionally, each transmitting unit also includes a gating switch, through which each transmitting input port for transmitting non-ultra-high frequency signals can be switchedly connected to multiple second antenna ports, so that the multiple second antenna ports respectively support the transmission of multiple signals in different frequency bands.
[0065] In one embodiment, if Fig. 9 As shown, the second RF device 30 includes: at least one transmission channel 310, a plurality of receiving units 320 ( Fig. 9 The example is illustrated with one transmission channel, four receiving units 320 and a third selection unit 330 .
[0066] At least one transmission channel 310, each transmission channel is connected to a transmission port, and is used to transmit the ultra-high frequency signal from the first radio frequency device 20 to any antenna; multiple receiving units 320, each receiving module is connected to a first receiving output port, and is used to support receiving and processing of the received ultra-high frequency signal; a third gating unit 330, multiple first ends of the third gating unit 330 are respectively connected to at least one transmission channel 310 and multiple receiving units 320, and multiple second ends of the third gating unit 330 are respectively connected to multiple antenna ports. The third gating unit 330 is used to switchably select and conduct the connection between at least one transmission channel 310 and any antenna, and is also used to select and conduct the connection between each receiving unit 320 and an antenna port.
[0067] Each transmission channel is connected to the first RF device 20 through a transmission port to receive the UHF signal to be transmitted from the first RF device 20, and is switchably connected to any antenna through the third selection unit 330 to realize switchable transmission of multiple antennas. Further, the switchable transmission of multiple antennas can include the transmission of multiple antennas in turn, thereby realizing the function of rotation transmission.
[0068] Each receiving unit 320 is connected to the RF transceiver 10 through a first receiving output port to transmit the received UHF signal to the RF transceiver 10; each receiving unit 320 is also connected to the antenna through the third selection unit 330 to receive the UHF signal from the antenna. Optionally, each receiving unit 320 may include a low noise amplifier to support low noise amplification processing; optionally, each receiving unit 320 may include a low noise amplifier and a filter to support low noise amplification processing and filtering processing.
[0069] The second RF device 30 of this embodiment can realize the transmission of the ultra-high frequency signal to be transmitted and the switching and gating function of multiple antennas through at least one transmission channel 310, multiple receiving units 320 and a third gating unit 330. It can also realize multi-channel reception of ultra-high frequency signals, which can greatly reduce the occupied area of the circuit board, improve the integration of the device and reduce the cost; at the same time, it can greatly reduce the routing between discrete receiving devices, transmitting devices and antenna switching switches, etc., and greatly reduce the complexity of the internal wiring of the communication equipment.

[0117] In one embodiment, if Fig.13 As shown, the communication device also includes: a radio frequency processing circuit 40 ( Fig.13 The second radio frequency device is not shown).
[0118] The RF processing circuit 40 is respectively connected to the RF transceiver 10, multiple second antenna ports and multiple antennas, and is used to support the transmission and reception selection of non-UHF signals, which include at least one of low frequency signals, intermediate frequency signals and high frequency signals.
[0119] The RF processing circuit 40 is respectively connected to the RF transceiver 10, the first RF device 20 and multiple antennas, and can support the selection of receiving and transmitting non-UHF signals. For example, it can be selected to transmit the non-UHF signal of the preset frequency band after the transmission processing by the first RF device 20, or it can be selected to receive the UHF signal of the preset frequency band from the antenna. The non-UHF signal includes at least one of a low frequency signal, an intermediate frequency signal and a high frequency signal. Therefore, through the first RF device 20, the second RF device 30 and the RF processing circuit 40, the communication device can support the selection of transmitting and receiving UHF signals and at least one of the low frequency signal, the intermediate frequency signal and the high frequency signal, so as to be compatible with the transmission and reception processing of each RF signal of different frequency bands, and improve the flexibility of the communication frequency band of the communication device.
[0120] In one of the embodiments, please refer to Fig.13 (The second RF device 30 is not shown in the figure), the RF processing circuit 40 includes: a first receiving module 410 , a second receiving module 420 and a transceiver selection module 430 .
[0121] The first receiving module 410 and the second receiving module 420 are respectively used to support receiving and processing of received non-ultra-high frequency signals; the transceiver selection module 430 is respectively connected to the second antenna port, multiple antennas, the first receiving module 410 and the second receiving module 420, and is used to switchably select and conduct the connection between the first RF device 20 and the target antenna and the connection between the first receiving module 410 and the target antenna, so that the target antenna supports the transmission and reception of non-ultra-high frequency signals, and the target antenna is one of the multiple antennas; it is also used to select and conduct the connection between the second receiving module 420 and another antenna among the multiple antennas, so that the other antenna supports the reception of non-ultra-high frequency signals.
[0122] Among them, the first RF device 20 and the first receiving module 410 can be connected to the target antenna together through the transceiver selection module 430, so that the target antenna supports the transmission and reception of non-ultra-high frequency signals. Optionally, the target antenna is used to support the transmission and main set reception of non-ultra-high frequency signals. Thus, the transceiver selection module 430 can select an antenna with higher antenna efficiency as the target antenna to improve the RF performance of the transmission and main set reception of non-ultra-high frequency signals.
[0123] Among them, the second receiving module 420 can be connected to another antenna among the multiple antennas through the transceiver selection module 430, thereby supporting another reception of non-ultra-high frequency signals based on the antenna, such as diversity reception of non-ultra-high frequency signals. Therefore, based on the first receiving module 410, the second receiving module 420 can support main diversity reception of non-ultra-high frequency signals, thereby improving the channel capacity of the communication equipment.
[0124] Furthermore, the transceiver selection module 430 can switchably select and conduct the connection between the corresponding second antenna port in the first RF device 20, the corresponding receiving input port of the first receiving module 410 and the target antenna, thereby simultaneously selecting non-ultra-high frequency signals in the target frequency band for transceiver while realizing antenna switching.
[0125] In one embodiment, if Fig.14 As shown, the second RF device 30 is connected to the first antenna (ANT1 in the figure) and the second antenna (ANT2 in the figure); the transceiver selection module 430 is connected to the fifth antenna (ANT5 in the figure) and the sixth antenna (ANT6 in the figure), respectively, and the communication device also includes: a first combining module 50 and a second combining module 60.
[0126] A first combining module 50, wherein a first end of the first combining module 50 is connected to a third antenna (such as ANT3 in the figure), and two second ends of the first combining module 50 are respectively connected to an antenna port of the second RF device 30 and a first receiving module 410, for combining ultra-high frequency signals and non-ultra-high frequency signals; a second combining module 60, wherein a first end of the second combining module 60 is connected to a fourth antenna (such as ANT4 in the figure), and two second ends of the second combining module 60 are respectively connected to another antenna port of the second RF device 30 and a second receiving module 420, for combining ultra-high frequency signals and non-ultra-high frequency signals.
[0127] Among them, each combining module can be used to combine multiple signals of different frequency bands to support signal reception and transmission. Specifically, the combining processing includes power synthesis of two or more signals and then transmitting them through the antenna, and also includes dividing one carrier signal into multiple signals for corresponding transmission to multiple antenna ports for reception, thereby realizing downlink carrier requirements.
[0128] For example, in this embodiment, the first combining module 50 can be used to divide the ultra-high frequency signal and the non-ultra-high frequency signal received by the third antenna into multiple signals, and transmit them to the second RF device 30 and the first receiving module 410 respectively; the second combining module 60 is used to divide the ultra-high frequency signal and the non-ultra-high frequency signal received by the fourth antenna into multiple signals, and transmit them to the second RF device 30 and the second receiving module 420 respectively.
[0129] Optionally, each combiner module may select a corresponding two-way combiner, three-way combiner, etc. according to the number of ports connected.
[0130] Therefore, through each combining module, the second RF device 30, the first receiving module 410, the second receiving module 420 and each antenna, the communication device can realize the combined transmission of multiple signals and also meet the downlink carrier demand.
[0131] In one of the embodiments, based on the above embodiment, the communication device is used to support the transmission of non-ultra-high frequency signals and 4*4 MIMO reception through the first antenna, the second antenna, the third antenna and the fourth antenna, and is also used to support the transmission of ultra-high frequency signals and 4*4 MIMO reception through the third antenna, the fourth antenna, the fifth antenna and the sixth antenna.
[0132] On the one hand, the third antenna and the fourth antenna are multiplexed as receiving antennas for UHF signals and non-UHF signals, which can reduce the number of antennas and reduce the number of wiring between the second RF device 30, the first receiving module 410, the second receiving module 420 and the antennas, respectively, further reducing the complexity of wiring; on the other hand, based on the aforementioned six antennas, the communication device can support the transmission of UHF signals, non-UHF signals and 4*4 MIMO reception of each signal, which can greatly improve the channel capacity of the communication device and improve the communication performance of the communication device.

Therefore, this embodiment only needs two ELNA devices to respectively realize multi-band reception of low-frequency signals, intermediate-frequency signals, high-frequency signals and other signals. Further optionally, please continue to refer to Fig.15 , the first receiving module 410 and the second receiving module 420 may include a plurality of low noise amplifiers, a gating switch, etc., respectively, thereby realizing multi-band reception of various signals such as low frequency signals, intermediate frequency signals, and high frequency signals. Compared with the related art that needs to realize corresponding functions through a plurality of discrete low noise amplifiers, gating switches, etc., this embodiment can further greatly reduce the occupied area of the circuit board, improve the integration of the device, reduce the cost, and reduce the complexity of the internal wiring of the communication device.

[0136] Thus, the fourth selection unit 431 can be used to switchably connect the transmit / receive selection unit 432 and the receive selection unit 433 to different antennas, such as the first antenna and the second antenna; the transmit / receive selection unit 432 can be used to select the non-ultra-high frequency signal of the target frequency band for transmission between the first RF device 20 and the fourth selection unit 431, and between the first receiving module 410 and the fourth selection unit 431; the receive selection unit 433 can be used to select the non-ultra-high frequency signal of the target frequency band for transmission between the second receiving module 420 and the fourth selection unit 431.
[0137] Furthermore, if Fig.15 As shown, the transceiver selection unit 432 may include a first filter unit 4321 and a transceiver gating device 4322 , and the receive selection unit 433 may include a second filter unit 4331 and a receive gating device 4332 .

[0139] The transceiver gating device 4322 is used to select and conduct the connection between the duplexer of the corresponding frequency band in the first filtering unit 4321 and the fourth gating unit 431, so that the duplexer of the corresponding frequency band can filter the non-ultra-high frequency signal to be transmitted and the non-ultra-high frequency signal to be received and processed, and isolate the transceiver path; the receiving gating device 4332 is used to select and conduct the connection between the duplexer of the corresponding frequency band in the second filtering unit 4331 and the fourth gating unit 431, so that the duplexer of the corresponding frequency band can filter the non-ultra-high frequency signal to be received and processed.
[0140] Further optionally, if Fig.15 As shown, the transceiver gating device 4322 and the receiving gating device 4332 can be understood as TX Modules to support the switching function of the switch; the first filtering unit 4321 and the second filtering unit 4331 can include duplexers or filters to support the filtering processing function.
