Abstract:
In one embodiment, an apparatus includes: a transmit path to receive, process and output a transmit radio frequency (RF) signal, the transmit path including a first power amplifier; a receive path to receive, process and output a receive RF signal, the receive path including a first low noise amplifier (LNA); and switching circuitry coupled to the transmit path and the receive path. In a transmit mode, the switching circuitry is to cause a RF filter to couple into the transmit path to filter the transmit RF signal and cause the filtered transmit RF signal to be provided to the first power amplifier and thereafter to an antenna. In a receive mode, the switching circuitry is to cause the receive RF signal to be provided to the RF filter and the first LNA, and thereafter to be provided to a digital processor.
