Filtering in the ETS-V transponder for mobile communications experiment
Abstract
The Japanese ETS-V (Engineering Test Satellite V) realized an experimental mobile satellite communications system via a transponder called AMEX (Aeronautical Maritime Experimental Transponder). The L band is used for the mobile link and the C band for the feeder link. For the L-band two-beam system, routing and filtering are performed through 12 SAW filters and four switches in the IF part. Filtering to prevent EMC problems is also studied for AMEX. AMEX shows good performance in orbit and is being used for a variety of mobile communication experiments by many organizations, including Communications Research Laboratory.
