Abstract:
A transceiver for use in a wireless device. The transceiver may include a receive portion for receiving an input RF signal. The receive portion may include at least one receive filter which may include a first filter. The transceiver may also include a transmit portion for transmitting an output RF signal. The transmit portion may include at least one transmit filter, which may include the first filter used in the receive portion. The transceiver may further include a plurality of switches, which may include a first switch coupled to an input of the first filter and a second switch coupled to an output of the first filter. The plurality of switches may be configurable to enable use of the first filter in the receive portion for receiving the input RF signal and use of the first filter in the transmit portion for transmitting the output RF signal.
