Abstract
An RF front end provides high receive selectivity by selectively configuring matching networks within a Time Division Duplex transceiver. One or more elements of the transmit or receive signal paths are configured to perform multiple functions. Each of the functions can be performed in dependence on an operating mode of the RF front end. In some embodiments, one or more elements in the transmit or receive signal paths are reconfigured during receive portions of operation to provide additional receive selectivity.
