Abstract :
A low-noise hybrid integrated millimeter-wave receiver which consists of a local oscillator and a down converter on a silica substrate is described in this paper. The source for the local oscillator is a Gunn diode and the mixer element is a Schottky barrier diode. A novel filter circuit is used to combine the local oscillator and the signal with low insertion loss in the signal path. The measured single sideband noise figure of the RF receiver at 30 GHz is 4.7 dB and the rms FM frequency variation due to the local oscillator is 168 Hz/¿khz.
