Abstract
Performance repeatability, thermal properties, and effects of biasing are studied on two Ka-band quasi-optical slot amplifier arrays fabricated with commercial MMICs on 254-/spl mu/m aluminum-nitride substrates. The unit cells are arranged in a 6/spl times/6 triangular lattice to suppress sidelobes. The amplifier arrays have peak small-signal gains of 2.1 dB at 31.02 GHz and 6.5 dB at 31.40 GHz, respectively.
