Abstract
A parametric surface‐wave amplifier capable of net terminal gain and an electronic gain of 15 to 25 dB is described. The amplifier consists of a three‐frequency lumped‐element varactor parametric amplifier attached to the electrical port of an interdigital surface‐wave transducer. Less than 2 mW of pump power is required and a bandwidth of about 0.6 % at 106 MHz is achieved.Keywords
