21) These are the fundamental component, Eq. 19), the second-order intermodulation component, Eq. 20), and the third-order intermodulation component, Eq. 21). Due to mismatches in real designs, the distortion that originates from the second-order nonlinearities must be taken into account, even in differential circuits (even components fractional matching below 1% can be critical ). , homodyne receivers). This phenomenon is referred to as second-order intermodulation distortion . 2. Performance Parameters of RF Circuits 21 As third-order intermodulation products are located near the desired signal, it is often difficult to filter them out without affecting the information content.
