Title: An Integrated 20-26 GHz CMOS Up-Conversion Mixer with Low Power Consumption
Abstract: A fully integrated 20-26 GHz broadband up-conversion mixer with low power consumption is demonstrated on 90nm CMOS technology in this paper. This mixer has a single-ended input and a multi-layer Marchand balun is used for converting the output of the single-balanced Gilbert cell topology to a single-ended output. This balun employs capacitive coupling between two metal layers and includes slotted shields to reduce substrate losses. The die size is 650μm×570μm. 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. Input referred 1-dB compression point is -14.8 dBm. The LO and RF return loss are better than 10 dB for frequencies between 20-26 GHz.
