A gilbert mixer with passive balun for 18 GHz Application

The aim of this paper is presented A Gilbert mixer with passive balun for 18 GHz application. It was used Taiwan Semiconductor provided by TSMC CMOS 0.18 µm process. We proposed mixer consists of Gilbert Cell, balun and the IF buffer amplifier. Finally, at the operation voltage of V
dd
= 1.8 V, RF frequency =18 GHz, LO frequency =17 GHz, the conversion gain is about 8.6 dB, input P1dB and power consumption are about −9 dBm and 41.4 mW. The chip size including all testing pads is 0.76 × 0.59 mm
