Abstract

The idea is to miniaturise and integrate a differential-input-differential-output mixer circuit at low local-oscillator input power while offering high isolation, low emission, high output third-order intercept-point, good spurious characteristics and frequency-selective conversion gain using the least number of components. Up to now Gilbert-Cell mixers with single-ended output of the mixer with separate stabilisation, matching and filtering circuits are used.
