An active balun is used to cancel the 3rd-order intermodulation (IM3) power in larger RF/IF power region of the mixer. In addition, by using the stabilized design in the IF inverter buffer amplifier, the stability of the proposed structure at high frequency can be improved by sacrificing very little gain. The measured conversion gain is-0.5\pm 2dB with operating frequency that covers from 16 to 53 GHz, and the measured IP1dB/IIP3 are-1.5/20 dBm and 0/21 dBm at 28 and 38 GHz, respectively. In addition, the measurement result of quadrature amplitude modulation (QAM) demodulation is presented. The mixer consumes only 5.9-mW dc power, including the buffer and active balun, with a compact chip area of 0.51× 0.67mm2. © 2021 IEEE. |
