Asymmetric mechanisms of second-order intermodulation in downconversion mixers

This paper addresses the issue of second-order intermodulation mechanisms with memory effects in downconversion mixers. In particular, an attempt is made to explain asymmetries in generated distortion caused by interferers situated below and above the local oscillator frequency. The analysis is carried out on a circuit level using Volterra-series techniques and provides an insight into underlying frequency-dependent mechanisms.
