ABSTRACT:
A high frequency switch module can handle transmit-receive signals of different frequency bands and realize excellent isolation. The high frequency switch module comprises a discriminating filter, a low-band high frequency switch, and a high-band frequency switch, wherein high-band 90-degree phase shifter that forms at least a high-band high frequency switch is configured by a high-pass filter, and a choke line is parallel-connected to the high-pass filter.
