Abstract
A quasi-optical amplifier array designed for K u-band operation is pre sented. Orthogonal monopole-probe antennas are used to couple the powe r into, and out from, an array of microstrip-based amplifiers. The arr ay has a gain of 5.4 dB at 16.4 GHz using packaged high electron mobil ity transistors (HEMT's), This gain is 3.5 dB below the maximum stable gain for this device at this frequency.
