Counter Intermodulation Distortion aka 4FMODs
4FMODs and Counter IM3 New to transmitter design? Trying to understand what metrics are used by industry for transmitter design? You might have heard of primary 4FMOD (also called CIM3) and secondary 4FMOD (also called CIM5). Unlike traditional IM3 which is generated by intermodulation of two tones, CIM3 and CIM5 are primarily generated by distortion […]
Intermodulation of Two Tones
Intermodulation of Two Tones Admit it. You are lazy and don’t make notes. You do this math every time you need to remember what distortion products are generated by intermodulation of two tones and what is their relative level. No more. We are doing the math now, so you don’t have to. Intermodulation Math Assume […]
