Abstract: A transceiver system may include a transmitter, a receiver, an antenna port that is connectable to the transmitter or to the receiver, a filter send port, and a filter return port. The filter ports may be antenna-side or receiver-side, and connectable across at least one filter between the antenna port and the receiver. A transceiver apparatus may include a housing including the transmitter, the receiver, a transceiver switch, and a filter switch assembly in a chamber of the housing. The ports may be accessible through a wall of the housing. A method for filtering a signal include switching, in response to a first signal, a receiver or a transceiver of a transceiver system from an unfiltered path connected to the antenna port to a filtered path connected to the antenna port. The method may further include switching, in response to a second signal, the receiver to the unfiltered path.
