WebIntroduction to n th order Intercept Point (IPn) with frequency translation circuits. The IPn, or n th-order intercept point is an important parameter used to evaluate the linearity of systems such as LNAs, mixers and amplifiers.The most commonly used is IP3. Consider the Taylor expansion of a generic transfer function G(x) of a non-linear circuit: Web21 feb. 2024 · Non-linearities in primarily the active devices in the system will create the IM3 distortion products as shown: The frequency difference between the two fundamental tones is also the frequency difference between the distortion products and their closest fundamental tone.
