A 50-GHz compact communication system for video link fabricated in MIC

A high-performance millimeter-wave communication system in the 50-GHz band was realized by using GaAs FET microwave integrated circuits. The system contains a 25-GHz dielectric resonant oscillator, a 25-GHz FM modulator, and 25/50-GHz frequency doublers. A transmitting power of 10 dBm and a receiver noise figure of 13 dB were obtained. A frequency stability of less than +or-100 p.p.m. was obtained over the temperature range from -20 degrees C to 60 degrees C.<<ETX>>
