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 ...
The air-interface of a multi-standard receiver can be described by Figure 1. The RF input covers a wide range of RF frequency bands. Each standard has its own RF band and channel spacing. In this ...
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 ...
Passive intermodulation (PIM) distortion arises when non‐linearities and imperfections within electrical connectors and transmission lines cause the intermodulation of signals, leading to spurious ...
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.
