Introduction
Abstract
Power amplifier designs for mobile handsets are becoming more complex, which directly impacts test demands
and the cost of test. Complexity increases with the introduction of new, wider bandwidth standards and the
addition of the number of radios to each device. At the same time, demand for improved battery life is driving
efficiency improvements, such as digital pre-distortion and envelope tracking. Business issues, such as pressure
on prices of these devices places greater demands on engineering teams producing power amplifiers.
Engineers who test mobile power amplifiers and front end modules on the production line are looking for solu-
tions to reduce test cost through maximizing throughput while ensuring that the devices meet required perfor-
mance levels.
This application note provides an overview of the key issues in a power amplifier and front end module test sys-
tem related to the RF signal analyzer and generator.
