Novel compact double balanced coplanar active mixer Application to a single chip MMIC receiver for satellite repeater

Abstract

This paper proposes a new compact double balanced coplanar mixer suitable for satellite repeaters. Compared to the present 14/12GHz satellite mixers, its size is divided by 3 and it provides 2dB gain instead of the classical 10dB loss. This mixer was successfully integrated with 4 other functions in a single chip receiver MMIC
