Design and performance of low-current GaAs MMICs for L-band front-end applications

Abstract

GaAs monolithic microwave integrated circuits (MMICs) with very low current and of very small size have been developed for L-band front-end applications. The MMICs fully employ lumped LC elements with uniplanar configurations. There are two kinds of MMICs: a low-noise amplifier and a mixer. The low-noise amplifier has a noise figure of 2.5 dB and a gain of 11.5 dB. The mixer has a conversion gain of 12.5 dB small local oscillator (LO) power of -3 dBm. Total current dissipation of the two MMICs is less than 8 mA with 3-V drain bias voltages.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
