An Optimized 18-26 GHz, Flat Gain, Balanced FET Amplifier using Commercially Available Transistors

A 18-26 GHz balanced amplifier in microstrip technology is presented. The amplifier stage uses only one FET having two 150 ?m wide cells, each of them being connected in each path of the balanced stage. The module achieves a gain of 5 dB an input and output VSWR less than 2 : 1 and a noise figure less than 7 dB.
