New App Note (Jan 2015): Introduction to Passive Intermodulation (PIM) Testing

 

Presented by AR - This app note is an introduction to PIM Testing. Passive Intermodulation (PIM) is a type of intermodulation distortion that can occur when two or more relatively high power signals exist within a system. PIM arises from electrical nonlinearities within the system, which act as unintentional mixers. Download this informative app note to learn more about this … [Read more...]

Incorporating Antenna VSWR Loss into the Simplified Method

 

The Simplified Method of Establishing the RF Power Required by a RF Immunity System Continued...Previously we presented the novel idea that the RF power required by a RF immunity system is a base RF power level (determined entirely by constants), minus the gain of the antenna. The basic principle is shown pictorially in Figure 1. The picture says the system RF power requirement … [Read more...]
