Abstract :
Experiments are described for a surface acousto-electric amplifier utilizing a composite spatially adjacent structure of lithium niobate and a silicon film. Principal observations include 6 dB stable terminal gain at 107 MHz with dc drift field power of 7W, electronically variable attenuation of 100 dB, and net electronic gain up to 1200 MHz. The use of the silicon film as a nonreciprocal Rayleigh wave transducer is also described.
