K-BAND SINGLE BALANCED MIXER WITH HIGH P1dB COMPRESSION USING 0.18μm CMOS PROCESS

摘要

K-band single balanced mixer based on Gilbert type using 0.18μm CMOS process is presented. For the circuit design, passive lumped elements such as a spiral inductor and a MIM capacitor are tested up 40 GHz. The designed mixer has a conversion gain of 2.3 dB and a PUB of -3 dBm at 24 GHz, It dissipates the power of 30.6 mW with 1.8 V supply voltage and the overall size is 940 × 560μm{sup}2.
