Abstract :
Multichip monolithic-integrated circuit modules that provide low-noise amplification, bandpass filtering, square-law detection, and DC amplification of a broadband millimeter-wave signal are described. The module is compact (4.50 cm/sup 3/) and lightweight (37 g), has low power consumption (80-130 mW), and is well-suited for use in focal-plane arrays to provide passive imaging of millimeter-wave thermal radiation. The theoretical gain requirement, radiometer construction, and measured results are reported.<>
