Let’s take an amplifier and feed it with two test signals of identical amplitude, but of two different frequencies which we will call “f1” and “f2”. Since the amplifier is non-ideal, there will be ...

The mixer generates intermediate freqeuency (IF) signals that result from the sum and difference of the LO and RF signals combined in the mixer: These sum and difference signals at the IF port are of ...

Passive intermodulation (PIM) distortion arises when non‐linearities and imperfections within electrical connectors and transmission lines cause the intermodulation of signals, leading to spurious ...

Q: What is passive intermodulation (PIM)? A: PIM is the generation of interfering signals caused by nonlinearities in the mechanical components of a wireless system. Two signals mix together ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

Two unique, real-world cases of interference in the FM band will be discussed by David Maxson, owner of Isotrope LLC, on the Tuesday afternoon of the upcoming Broadcast Engineering Conference at the ...

Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...
