Abstract

Describes the design and performance of an 8-GHz MMIC (monolithic microwave integrated circuit) MESFET (metal-semiconductor FET) power limiter. This limiter incorporates a special gate biasing scheme and makes use of appropriate load conditions which reduce the unexpected phase variations experienced by the signal through the device. Measured performances (phase variations less than 8 over a 22-dB input power range) are found to be in agreement with the theoretical ones obtained from large signal simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
