Abstract
An apparatus comprises a transmit network to transmit an input from a first amplifier to an antenna, a receive network to provide an input from an antenna to a second amplifier, a first switch to selectively decouple the transmit network from the antenna, and a second switch to selectively decouple the receive network from the antenna. Other embodiments may be described.
