Abstract
A matrix distributed amplifier, having a gain of 20 dB with a noise figure of 5 dB in the frequency range between 0.5–12 GHz, is presented. The amplifier, realised in hybrid technology using commercially available GaAs HEMTs, incorporates a novel scheme which allows the biasing of a single stage of the two tier amplifier (two rows of active devices) with a unique controlling resistance and, at the same time, the cascading of the two FETs of each stage. The computed results obtained using a small signal model for each FET fit rather well with the measurements in the whole frequency range.Keywords
