This paper describes the design and measurement of a double‐balanced monolithic star mixer using a double planar baluns with a Marchand section followed by a coupled‐line structure. The microwave and millimeter‐wave integrated circuits (MMICs) are fabricated on commercially available InGaAs/AlGaAs pseudomorphic high‐electron‐mobility transistor (PHEMT) processes with a chip size of 1.43 × 1.28 mm 2 . The typical up‐conversion loss is 7 dB with an LO‐to‐RF isolation better than 28 dB. © 2004 Wiley Periodicals, Inc.
