ABSTRACT:
A RF circuit includes a master PCB, a plurality of slave PCBs and a plurality of antennas. The master PCB includes at least two RF ICs and at least two transceiving diplexer groups for tranceiving different frequency bands. Each transceiving diplexer group includes a plurality of transceiving diplexers transceiving a same frequency band and electrically connected to the RF ICs via PCB tracks without intersection. Each slave PCB includes a frequency division diplexer electrically connected to at least two transceiving diplexers respectively belonging to different tranceiving diplexer groups for respectively transmitting different frequency bands. Each antenna electrically connects to one of the division diplexers.
