Abstract
A band selection switch circuit for an amplifier with an impedance matching circuit includes a band selection switch and an impedance compensation circuit. The band selection switch includes a signal port switch configured to selectively connect to one of a common transmit port, transmit and receive (TxRx) ports, and receive ports, and an impedance port switch configured to selectively connect the common transmit port and one of the receive ports and an impedance port. The impedance compensation circuit includes an impedance element connected to the impedance port.
