Abstract

A dual-channel downconverter has been developed targeted for the Direct Broadcast Satellite Television market. In the established European and the developing North American DBS markets, the system design utilizes dual-polarized signals for program transmission. To reduce the receiver complexity it is desirable to have a monolithic dual-channel downconverter that minimizes parts count and reduces assembly/manufacturing costs while maintaining, and perhaps improving total system performance. This was the motivation for developing a GaAs MMIC dual-channel downconverter.<>
