This paper fabricates a K-Band 24 GHz high-gain, low-power down-conversion mixer using a standard TSMC 0.18-μm CMOS technology. The architecture that is used is based on that of a Gilbert cell mixer. Transformer coupling technology is used at the node between the transconductance stage and the local oscillator switches stage. The conversion gain, the noise figure and the size of the chip area performance are significantly better, so this mixer with specific RF parameters gives excellent performance. The simulation (post-sim) results for the proposed mixer show a 15–19 dB power conversion gain, a − 8.3 dBm input third-order intercept point (IIP3) at 24 GHz, a 10–12.3 dB signal side band (SSB) noise figure and an RF bandwidth of 20–26 GHz. The core power consumption for the mixer is 3.096 mW and the output buffer power consumption is 3.122 mW. The total dc power consumption for this mixer, including the output buffers, is 6.22 mW. The total chip size for the K-Band mixer is 0.95 × 1.14 mm2.
