Abstract :
This paper presents a 50 GHz-band high gain monolithic balanced gate mixer. Conversion gain of the mixer is improved by using an external IF balun with high impedance transforming ratio. This paper shows that the IF impedance of the balanced gate mixer can be approximated from a small signal equivalent circuit. The maximum conversion gain of 8.2 dB is achieved at a LO power of 0 dBm. The effectiveness of the described mixer is confirmed experimentally
