Abstract
We report a wideband resistive mixer fabricated in 65-nm CMOS for 60-GHz frequency range. The local oscillator signal balancing is implemented with an on-chip spiral balun. The broadband response of the balun enables wideband local oscillator tuning range. The mixer topology is suitable for both up- and downconversion. We present the on-wafer measurement results in both of these mixing modes. In downconversion, the mixer achieved 12.5 dB of conversion loss and +5 dBm of 1-dB input compression point. In upconversion, the measured conversion loss was 13.5 dB with -19 dBm of 1-dB output compression point. The local oscillator suppression was better than 34 dB for an LO frequency from 51 to 62 GHz. The size of the mixer including pads is 0.47 mm2.Keywords
