Air interface Peak to Average
The collection of data here reflects air interface standards I've worked on and their respective amplitude statistics.When designing a small signal circuit block, PA or entire lineup, it is important to understand the nature of the signals flowing through them. This table of data is a quick stop reference guide to assist design.
