In this paper, we present the development of an advanced MMIC receiver for a 94-GHz band passive millimeter-wave (PMMW) imager. Our configuration is based on a Dicke receiver in order to reduce fluctuations in the detected voltage. By introducing an electronic switch in the MMIC, we achieved a high resolution millimeter-wave image in a shorter image collection time compared to that with a conventional mechanical chopper. We also developed an imaging array using MMIC receivers.
