Classification: H04B

Abstract:
A transreceiver architecture comprising:an antenna capable of transmitting and receiving signals;a forward channel filter, having a signal input end and a signal output end, said forward channel filter tuned to permit passage of forward channel frequencies and electrically coupled at said signal input end to said antenna;a reverse channel filter, having a signal input end and a signal output end, said reverse channel filter tuned to permit passage of reverse channel frequencies and electrically coupled at said signal input in to said antenna in parallel with said signal input end of said forward channel filter;a TDD transmit switch having an open and closed position and having a signal input end and signal output end, said signal input end electrically coupled to said signal output end of said forward channel filter;an FDD-TDD switch having an open and closed position and having a signal input end and signal output end said signal input end electrically coupled to said output end of said forward channel filter and in parallel with said input end of said TDD transmit switch and said signal output end electrically coupled to said signal output end of said reverse channel filter; anda TDD receive switch having an open and closed position and having a signal input end and signal output end, said signal input end electrically coupled to said signal output end of said reverse channel filter and electrically coupled to said output end of said FDD-TDD switch.
