This paper presents a broadband image-reject mixer consisting of a wideband image reject mixer with active baluns. A switched transconductor mixer embedded with an active balun for the local oscillator (LO) signal is designed. An active balun for RF input signal with a RC parallel network to reduce gain and phase imbalance is proposed. Implemented in a 0.5μm InGaAs E-mode pHEMT, the mixer can achieve conversion gain of 9 dB, image rejection of 32 dBc, single sideband noise figure of 13 dB, and third-order input intercept point (IIP3) of 9 dBm over the entire frequency range of 0.5 to 5.5 GHz.
