Abstract

A microwave scale model of an amplifying element suitable for millimeter-wave quasi-optical arrays is presented. Power is guided into the amplifier by short sections of waveguide and then fed into a microstrip based MESFET amplifier with an E-field probe. A second E-field probe couples the output signal into a similar waveguide feed on the back-side of the element. The output waveguide is orthogonal to the input to achieve isolation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
