The second transmission path is directly connected to the single pole double throw switch SPDT via the single pole four throw switch SP4T, so that the transmission signal output from the transceiver 10 is transmitted to the antenna ANT1 and the antenna ANT2 via the second transmission path.

Referring to fig. 2, fig. 2 is a block diagram illustrating an exemplary structure of a radio frequency circuit according to a first embodiment of the present application.
As shown in fig. 2, in this embodiment, the transceiver 10 includes a first transmission module including a low frequency signal transmission port trc_lb_tx0, an intermediate frequency signal transmission port trc_mb_tx0, and a high frequency signal transmission port trc_hb_tx0.
Correspondingly, the second switch module includes a single pole double throw switch SPDT1 connected to the low frequency signal transmission port trc_lb_tx0, a single pole double throw switch SPDT2 connected to the intermediate frequency signal transmission port trc_mb_tx0, and a single pole double throw switch SPDT3 connected to the high frequency signal transmission port trc_hb_tx0.
When transmitting signals, the transceiver 10 outputs signals through only one signal transmission port in the first transmission module, and correspondingly forms one sub-transmission path.
A first sub-transmission path of the first transmission path is connected to the low frequency signal transmission port trc_lb_tx0, for example, through a single pole double throw switch SPDT 1; a second sub-transmission path of the first transmission path is connected to the intermediate frequency signal transmission port trc_mb_tx0, for example, through a single pole double throw switch SPDT 2; the third sub-transmission path of the first transmission path is connected to the high-frequency signal transmission port trc_hb_tx0, for example, through a single pole double throw switch SPDT3.
That is, a first end of each single pole double throw switch is connected to a corresponding transmit port, and a second end of each single pole double throw switch SPDT is connectable to the power amplifier PA and the transmit switch module TXM of the first transmit path 20. Therefore, the transmission signals output by the signal transmission ports of the first transmission module are transmitted to the antenna ANT1 and the antenna ANT2 through the power amplifier PA and the transmission switch module TXM and the single pole double throw switch SPDT and the double pole double throw switch DPDT on the sub transmission path corresponding to the first transmission path.
As shown in fig. 2, the third terminal of each single pole double throw switch may be connected to a single pole four throw switch SP 4T.
As shown in fig. 2, each end of the lower side of the single pole four throw switch SP4T is connected to the third end of each single pole double throw switch SPDT, and the upper side of the single pole four throw switch SP4T is connected to the single pole double throw switch SPDT common to the first transmission path 20 and the second transmission path 30.
A fourth sub-transmission path of the second transmission path is connected to the low frequency signal transmission port trc_lb_tx0, for example, through a single pole double throw switch SPDT 1; a fifth sub-transmission path of the first transmission path is connected to the intermediate frequency signal transmission port trc_mb_tx0, for example, through a single pole double throw switch SPDT 2; the sixth sub-transmission path of the first transmission path is connected to the high-frequency signal transmission port trc_hb_tx0, for example, through a single pole double throw switch SPDT3.
Therefore, the transmitting signals output by the signal transmitting ports of the first transmitting module can be transmitted to the antenna ANT1 and the antenna ANT2 through the single-pole four-throw switch SP4T, the single-pole double-throw switch SPDT and the double-pole double-throw switch DPDT on the sub transmitting path corresponding to the second transmitting path.
As shown in fig. 2, each input end on the left side of the power amplifier PA is connected to each single-pole double-throw switch of the second switch module, and the output end on the right side of the power amplifier PA is connected to the input end of the transmitting switch module TXM, and the output end of the transmitting switch module TXM is connected to the single-pole double-throw switch SPDT of the second switch unit.
Conventionally, a low-frequency signal transmitting port trc_lb_tx0, an intermediate-frequency signal transmitting port trc_mb_tx0 and a high-frequency signal transmitting port trc_hb_tx0 of a first transmitting module of the transceiver 10 input a transmitting signal of a target frequency band output by the first transmitting module to a power amplifier PA through a single-pole double-throw switch connected to the corresponding signal transmitting port, obtain a transmitting signal TRX after the power amplifying process of the power amplifier PA, transmit the transmitting signal TRX to a transmitting switch module TXM according to a duplexer B1 or B5 corresponding to the target frequency band, and transmit the signal to a corresponding antenna ANT1 and an antenna ANT2 through a single-pole double-throw switch SPDT and a double-pole double-throw switch DPDT which are connected in sequence by the transmitting switch module TXM.
The first transmit module of the transceiver 10 may switch to the second transmit path 30 when either one of the power amplifier PA and the transmit switch module TXM fails, resulting in a TX failure of the first transmit path 20. The low-frequency signal transmitting port trc_lb_tx0, the intermediate-frequency signal transmitting port trc_mb_tx0 and the high-frequency signal transmitting port trc_hb_tx0 of the first transmitting module inputs the transmitting signal of the target frequency band output by the transceiver 10 to the single-pole four-throw switch SP4T through the correspondingly connected single-pole double-throw switch SPDT, and then the single-pole four-throw switch SP4T forwards the transmitting signal to the correspondingly connected single-pole double-throw switch SPDT and transmits the transmitting signal to the corresponding antenna ANT1 or antenna ANT2 through the double-pole double-throw switch DPDT.
Similarly, in the conventional case, the signal received by the antenna ANT1 or the antenna ANT2 may be passed through the double pole double throw switch DPDT, the single pole double throw switch SPDT and the transmission switch module TRM to obtain the received signal TRX, and after passing through the duplexer B1 or B5, the received signal PRX is obtained, and then the received signal trc_rx is output to the first transmission module of the transceiver 10 after passing through the low noise amplifier PRX LNA.
When any one of the power amplifier PA and the transmitting switch module TXM fails, the signal received by the antenna ANT1 and/or the antenna ANT2 may directly output the signal DRX through the double pole double throw switch DPDT, and obtain two paths of received signals DRX through the grading module DiFEM, and then output two paths of received signals trc_rx to the first transmitting module of the transceiver 10 after passing through the low noise amplifier DRX LNA.
In the embodiment of the application, through the radio frequency circuit comprising the first transmitting path and the second transmitting path which are respectively connected with the transceiver, any path can be selected to transmit the transmitting signal to the antenna module, so that when one transmitting path fails, the transmitting path is switched to the other transmitting path to execute the TX function, and normal uplink communication is ensured.

The power amplifier and the transmission switch module process the transmission signal output by the transceiver 10, and the transmission signal is transmitted to the antenna ANT1 and the antenna ANT2 after being processed.
In case that the power amplifier or the transmission switching module fails to cause the TX function of the failed first transmission path 20 to fail, thereby causing the uplink communication to be interrupted, the transceiver 10 switches to the second transmission module trc_tx1 and transmits a signal via the second transmission path 30 connected to the second transmission module trc_tx1, performing the TX function.
