Abstract :
Single stage and double stage quasi-optical amplifiers are presented. The amplifiers are constructed on double layer back to back microstrip circuits with a shared ground plane. The ground plane provides an effective isolation between the receiving and the transmitting antenna arrays. Furthermore it serves as a heat sink in high power amplifier designs. The single stage quasi-optical amplifier had a gain of 7.54 dB at 10.04 GHz and the two stage quasi-optical amplifier had a gain of 18.0 dB at 9.95 GHz
