“…This mixer works very well for supply voltages as low as 1.9V. The transformer coupled mixer (TCM) design also appears in other publications [2,3,4]. To overcome the high SAW filter loss in wideband systems, higher than 10 dB power gain is required from the mixer.…”

A monolithic low noise high linearity LNAlMixer circuit for 2.5 GHz applications has been fabricated in IBM 47 GHz SiGe production process. The measured performance is 8 dBm input IP3,1.6 dB NF and 12 dB Gain for a low noise amplifier (LNA), and 2.5 dBm input IP3, 7.5 dB NF and 14 dB gain for a downconversion mixer with a total current consumption of 26 mA for a 2.75V supply. LNA matching, mixer RF and LO matching and two baluns are all integrated on chip, requiring no critical RF tuning components.
