Abstract

The authors propose a 30/20-GHz highly reliable and compact earth station to realize DYANET cost-effectively. DYANET is a network that uses both terrestrial networks for high-capacity transmission and satellite networks for diversified traffic transmission. To realize a reliable and cost-effective earth station, a phase-compensated carrier filter and a TDMA (time-division multiple-access) frame have been developed to realize transponder hopping systems by a single TDMA terminal per earth station. The authors describe the synchronization unit, the burst modem, and the terrestrial interface module. Using high-efficiency helix TWTA (traveling-wave to be amplifier) operating in the 30-GHz band, a high-efficiency power supply and up-and-down converters with transponder hopping capability have been developed.
