Abstract :
The operation, biasing, and measured results of a CMOS doubly balanced dual-gate downconversion mixer are presented. Measurements show, with a radio-frequency input of 1.9 GHz and an intermediate-frequency output of 250 MHz, that the mixer has a conversion gain of 0 dB, an input-referred third-order intercept point of +2 dBm, and a single-sideband noise figure of 13.6 dB while requiring +5 dBm of local-oscillator power and consuming 10.2 mA from a 3 V power supply
