Abstract :
A low-power, fully integrated 20-26 GHz broadband up-conversion mixer implemented with on-chip Marchand baluns is demonstrated on 90nm CMOS technology in this paper. The baluns employ capacitive coupling between two metal layers and include slotted shields to reduce substrate losses. At 22.1 GHz, the integrated mixer achieves a conversion gain of 2 dB with a maximum power dissipation of only 11.1mW from a 1.2V dc power supply at LO power of 5 dBm.
