Abstract :
A single-balanced Gilbert mixer intended for use in a superheterodyne receiver in the 57-64-GHz ISM band has been fabricated in SiGe bipolar technology. Using an output IF in the range of 8.3-9.1 GHz, the mixer achieves a voltage conversion gain >9 dB and an upper single-sideband noise figure <13 dB, with mixer core current consumption of 3.2 mA at 2.7 V. Total test-site current consumption, including an output buffer, is 19.2 mA.
