Title :
Control of Surface Acoustic Waves with Distributed Varactors
Abstract :
A distributed Schottky barrier varactor junction is described, capable of varying the electrical boundary conditions seen by a surface wave propagating on a piezoelectric medium. Control of the acoustic wave is evidenced by almost 180° of phase shift in 1.75 mm of interaction length at 54 MHz.
