Abstract
This paper presents a 50-GHz-band high-gain monolithic balanced gate m ixer. IF impedance of the balanced gate mixer is approximated from a s mall-signal equivalent circuit, and conversion gain of the mixer is im proved by using an external IF balun with high impedance-transforming ratio. The maximum conversion gain of 8.2 dB is achieved at LO power o f 0 dBm. Effectiveness of the described mixer is confirmed experimenta lly.
