Abstract
64 MMIC receivers built for mm-wave imaging have been systematically characterized. Each receiver comprises three InP MMIC low noise amplifiers and a biased Schottky diode detector in a compact package with a horn antenna. The characterization includes spectral response, responsivity and noise. The noise has both white and 1/f components. The average (±standard deviation) receiver bandwidth is 23.8±3GHz, and the overall noise equivalent temperature difference (NETD) in an integration time of 0.2ms, as used in the imager, is 0.66±0.1K.
