A PHEMT diode single-balanced mixer for K/K-band application

A single‐balanced mixer for operation in the microwave‐ and millimeter‐wave bands is presented. This monolithic microwave‐integrated circuit was implemented on AlGaAs/InGaAs/GaAs pseudomorphic high‐electron‐mobility transistor process with a chip size of 2.11 × 1.54 mm2. This mixer employs a planar...

Description
Summary:A single‐balanced mixer for operation in the microwave‐ and millimeter‐wave bands is presented. This monolithic microwave‐integrated circuit was implemented on AlGaAs/InGaAs/GaAs pseudomorphic high‐electron‐mobility transistor process with a chip size of 2.11 × 1.54 mm2. This mixer employs a planar Marchand balun and a low‐pass filter for isolating three ports corresponding to RF, LO, and IF ports. The best upconversion loss is 8 dB with an LO‐to‐RF isolation better than 30 dB. © 2007 Wiley Periodicals, Inc.
