Abstract
The letter reports the concept of a new switching/amplifying network, and its basic performance, for scanning the down-link beam rapidly in multibeam satellite systems. Experiments in the K-band have shown 85% power-combining efficiency, more than 17 dB isolation and 400 ns switching speed.
