Abstract
This paper describes 94-GHz band low-noise and high-gain amplifier MMICs using InP HEMTs, which have been developed for passive millimeter-wave (PMMW) imaging. To achieve a high gain with low noise performance, we propose a new stabilizing technique for the amplifier. The measured noise figure was 3.2 dB and the gain was 33 dB. In addition, we developed a PMMW imager using this amplifier. We also demonstrated an example of a millimeter-wave image acquired by the PMMW imager.Keywords
