Linearity Measurements on RFFE Components

Distortions caused by components in the RFFE (radio frequency front end) limit the performance and throughput of communications systems. Types of distortions include:

▪ AM-AM and AM-PM (complex variations of gain with amplitude)

▪ Non-linear frequency response (memory effect)

All RFFE components exhibit all of these distortions, only the proportions vary. In this Application Note, illustrative measurements of individual RFFE components, as well as a complete RFFE, will be made. This is followed by the documentation of a more complete analysis, including comparison against theoretical limits, of a linearized commercial SatCom BUC product.
