A transceiver apparatus for maximizing voltage. A voltage booster or transformer is implemented using piezoelectric thin films in substrates, preferably CMOS substrates where active processing of RF signals can lead to highly integrated and inexpensive ICs. The voltage gain is achieved by cascading multiple transducers, formed in the same piezoelectric thin film, or films cascaded in series on top of each other. An array of transducers are connected in parallel or series, connected to the input or output port electrodes. Other approaches include placing the receive transformer in a location where the diffracting field from the transmitter transducer is incident on the receive transducer generating a higher ultrasonic field at the receive transformer and increasing the voltage is to connect an array of transducers, formed in the same layer, or different layers of piezoelectric layer in parallel in drive mode when the pulse is transmitted.
