Abstract
A binary bi-phase shift modulator having an input piezoelectric transducer and an output piezoelectric transducer connected in series between a radio frequency input and a radio frequency output. A fixed DC pole voltage having a first polarity is connected to one of the transducers. A DC switched pole voltage is connected to the other transducer which switches between the pole voltage of the first polarity and a pole voltage of the opposite polarity in accordance with a binary data signal. The polarity of the radio frequency input relative to the radio frequency output varies as a function of the polarity of the DC switched pole voltage.
