In this brief a high linearity, low loss, downconversion mixer requiring low LO drive power is presented for use in 5G beamforming applications. The emitter degenerated Gilbert-cell mixer with a four-way power combiner, baluns, and output filter is implemented using a 130-nm SiGe BiCMOS technology. The measured input 1-dB compression point of the fully integrated mixer is 6.4 dBm with a conversion gain of -12.9 dB. The mixer consumes 29.7 mW during small-signal operation and has a core area of 0.99 mm2. The relatively low loss and high linearity performance of the core mixer makes it uniquely suitable for use in 5G receivers.
