A Low Noise Distributed Amplifier with Gain Control

A 2 to 18 GHz monolithic GaAs distributed amplifier has been developed with 17dB nominal gain, less than 2.0:1 input and output VSWR, Iess than 6.0dB noise figure, and greater than 40dB gain control . The chip size at 3.0 sq. mm. (1.63mm by 1.88mm) makes it cost effective for a wide variety of applications.
