Adjacent Channel Leakage Ratio (ACLR) Derivation for General RF Devices
The adjacent channel leakage ratio (ACLR) of any general purpose radio frequency (RF) device, whether a mixer, amplifier, isolator, or other device, is frequently dominated by the 3rd-order intermodulation distortion (IM3) of the device. The relationship between the IM3 performance and the output intercept point (OIP3) parameter of the device can be derived. This application note details a formula for the prediction of the ACLR performance as a function of this IM3 performance parameter.
