For example, referring to fig. 2, the first network mode is GSM, and the third network model is 5G. After the GSM _ LB signal is input into the second rf module 130, the GSM _ LB signal may be amplified again by the second signal amplifier 131 in the second rf module 130, and then radiated out through the second antenna 160 by the second output switch 135. In addition, the 5G low frequency (5G _ LB) signal can be input to the second rf module 130 from the rf transceiver 110, enter the second signal amplifier 131 for amplification after passing through the second input switch 133, and then directly radiate out through the second antenna 160 after passing through the second output switch 135.
