A uni-planar MMIC 26-GHz-band receiver

Abstract

A GaAs 26-GHz-band MMIC (monolithic microwave integrated circuit) receiver has been designed, fabricated, and evaluated. All MMICs in the receiver have uniplanar configuration. A coplanar waveguide is mainly used as a microwave transmission line, with air bridges successfully utilized. Total circuit area is sufficiently small so that single-chip integration is possible. Assembled MMICs show stable receiver performance, including a noise figure of 8 dB and conversion gain of 2 dB or more, without any adjustment or external tuning circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
