The target low frequency transceiving port 305 of group 10 .

Wherein, the full English name of the P port in the present application is Port (polarization) port, the appellation used for the port connecting the antenna in the multiplex switch in the present application, and the full English name of the T port is Throw (throwing, throwing), in the present application The name used for the port connected to the radio frequency module in the multiplex switch, such as 4P4T switch.

It should be noted that, Fig. 3 only schematically shows 3 T ports of SPXT switch, 2 medium and high frequency transceiver ports 304, 3 T ports of SPYT switch, 2 target low frequency transceiver ports 305, in actual application , depending on the actual values of X and Y, the number of SPXT switch T ports, the number of medium and high frequency transceiver ports, the number of SPYT switch T ports, and the number of target low frequency transceiver ports can be more or less, which will not be done here Specific limits.

Table 1

It can be seen that in this example, since the target low-frequency transceiver port and the medium-high frequency transceiver port are respectively connected to different selection switches, the transmitting module supports carrier aggregation of the target low-frequency signal and the target medium-high frequency signal. However, the target low-frequency transceiver port and the medium-high frequency transceiver port of the currently commonly used transmitting modules share a selection switch, and the transmitting module cannot simultaneously transmit the target low-frequency signal and the target medium-high frequency signal, that is, the current transmitting module does not support the target low-frequency Carrier aggregation for medium and high frequency signals.
