Antenna switch modules and methods of making the same

Abstract:

Antenna switch modules and methods of making the same are provided. In one implementation, an antenna switch module includes a first transmit and first receive port that are respectively connected to at least one antenna series switches. The first receive and transmit port receive and transmit signals on a first frequency. In one implementation, a second transmit and second receive port are connected to the at least one antenna and transmit and receive signals on a second frequency. In this implementation, the second receive port is connected to the at least one antenna via a series switch but the second transmit port is connected to the at least one antenna via a inductive resonance circuit that provides impedance to isolate the second transmit port when the first transmit port or receive port is transmitting or receiving via the at least one antenna.
