Abstract :
A novel millimeter-wave quasi-optical amplifier array architecture is presented. The amplifier array consists of a horn antenna that tapers down to a parallel-plate waveguide. Stacked between the parallel-plates is a microstrip power divider circuit which feeds the active elements. At the output there is a similar power-combining circuit and transition to free space. Measurements on the active array show a maximum gain of 7.25 dB at 43.25 GHz and a bandwidth of 5.75 GHz
