ABSTRACT:
A multi-band transceiver has a function of sharing transmitted and received signals of multiple frequency bands by the same antenna. The multi-band transceiver mounts multiple filters that correspond to the multiple frequency bands and multiple amplifiers for amplifying the transmitted signals on the same substrate, and arranges the multiple filters in close vicinity to the amplifier in the order where the multiple filters are excellent in their temperature characteristic.
