A single-balanced mixer for operation in the microwaveand millimeter-wave bands is presented. This monolithic microwaveintegrated 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.
