Abstract
Development is reported of a 50-GHz low-noise amplifier for a trial model of a millimeter-wave personal satellite communication system. The amplifier has a 3.0-dB noise figure and 22-dB gain at 50 GHz, including its input circulator and package interfaces. To design the amplifier, new equivalent circuit which effectively models the noise and scattering parameters of HEMTs is proposed.
