Abstract :
An X-band monolithic low noise amplifier (LNA) with 0.5- mu -gate pulse-doped GaAs MESFETs was successfully demonstrated for a direct-broadcast-satellite (DBS) converter. This LNA shows excellent voltage standing wave ratio (VSWR) matches of under 1.4 as well as a noise figure of 1.67 dB and a gain 24 dB at 12 GHz. The yield of chips within microwave specifications is 62.5%.<>
