WIDE BANDWIDTH TIME DIVISION DUPLEX TRANSCEIVER

Abstract:

A wide bandwidth time division duplex (TDD) transceiver includes a transmitter, a receiver, and a bandpass filter implemented with a plurality of acoustic resonators including at least one shunt resonator and at least one series resonator. A transmit/receive switch is configured to selectively connect a first terminal of the bandpass filter to either an output of the transmitter or an input of the receiver. Each of the plurality of acoustic resonators is a high power transversely-excite film bulk acoustic resonator.
