Abstract: The goal of this paper is to present the application of the monolithic microwave integrated circuits (MMICs) in the direct broadcast satellite (DBS) receivers. A brief history of MMICs in this area, availability and future trends are outlined. Typical MMICs for individual functions of low-noise down converter as well as fully monolithic multifunction down converter chips are considered
Key words: Microwave integrate circuit, WARC, DBS system, IF amplifier, mixer, MESFET, local oscillator, down converter.
