Abstract
An acoustic transformer in a transmitter chain is disclosed. In one aspect, a differential power amplifier may produce a differential signal that is provided to an acoustic transformer coupled to an acoustic filter. The acoustic transformer provides a single-ended output signal for use by the acoustic filter. To facilitate operation in multiple bands, multiple acoustic transformer-acoustic filter pairs may be provided with a switching network used to route the amplified signal to the appropriate transformer-filter pair.
