Evaluate the performance of RF power amplifiers

RF power amplifiers (PAs) can be specified in many different ways. Most customers expect to see industry-standard specifications when comparing products. But occasionally, manufacturers will list other performance parameters on their data sheets-parameters that enhance the apparent performance of their products or mask shortcomings. The best way for a specifier to avoid confusion is to rely upon accepted terminology and test methods. The following report should help amplifier specifiers interpret the meaning of key performance parameters.
