20-GHz bands receiving facilities at sub-earth-station for CS site diversity switching experiments
Abstract
Site diversity switching experiments using CS (Medium-capacity Communications Satellite for Expperimental Purposes) were programmed. The satellite communication facilities used in the experiments both at the main- and the sub-earth-station have been constructed in the ECS project. In addition, receiving facilities at 20-GHz bands of CS down-link were newly installed at the sub-earth-station. They were composed of an antenna feed, a low-noise receiver, and a down converter. In the present paper, the outline and the performance of the facilities added at the sub-earth-station are described. The performance of these facilities has proved to be good enough to carry out the experiments.
