HTS filter and front-end subsystem for GSM1800 wireless base station

The first HTS front-end subsystem for a wireless base station in China has been developed. This demonstration system, which is geared to application at the GSM1800 mobile communication base station, consists of a single RF path, i.e., one filter and one LNA, integrated with the pulse tube cooler.

Zusammenfassung:The first HTS front-end subsystem for a wireless base station in China has been developed. This demonstration system, which is geared to application at the GSM1800 mobile communication base station, consists of a single RF path, i.e., one filter and one LNA, integrated with the pulse tube cooler. The subsystem works at a pass band of 1710-1785 MHz with a gain of 18 dB and at a temperature of 70 K. The accomplishment of such a demonstration subsystem can boost the development of the HTS commercial subsystem.
