Development of a very small receive-only earth station for the 20 GHz frequency band
Abstract
In order to give new satellite communication services assured status, a very small receive-only earth station operating in the 20-GHz frequency band has been developed. This earth station consists of a receive antenna with a diameter of 30 cm, an HEMT low-noise receiver, and a CPFSK demodulator operating at 9.6 kbps. The antenna and the receiver are designed as a single unit, which can be used on a desk top and is easy to operate. The system noise temperature of the HEMT receiver is about 190 K at room temperature. The G/T of the station is 10.8 dB/K.
