Patent ID: 8064846

Claim:
A radio frequency (RF) circuit, comprising: a master printed circuit board (PCB) configured with at least two radio frequency integrated circuits (RF IC) and at least two transceiving diplexer groups respectively and electrically connected to the at least two RF ICs for transceiving different frequency bands, each transceiving diplexer group comprising a plurality of transceiving diplexers transceiving a same frequency band and electrically and commonly connected to one of the RF ICs via PCB tracks without intersection; a plurality of slave PCBs, each slave PCB being configured with a frequency division diplexer electrically connected to at least two transceiving diplexers respectively belonging to different transceiving diplexer groups for respectively transmitting different frequency bands; and a plurality of antennas each electrically connected to one of the frequency division diplexers; wherein the frequency division diplexers are electrically connected to the transceiving diplexers via coaxial cables.
