RF power amplifier testing

RF power amplifier testing

From wafer to design-in

Power amplifiers are a crucial part of any RF design. These essential components get the RF signal to the right power level for transmission and the strength the receiver needs to recognize and decode the signal. Various applications, from low noise amplifiers often used at receiver frontends to high power amplifiers used at larger broadcast systems, face challenges such as signal distortion, power consumption, and a variety of measurements and reruns.

Rohde & Schwarz solutions help you verify your design with unmatched RF measurement performance, dynamic low level power consumption analysis and high test speed.

Power amplifier efficiency optimization

Power amplifier efficiency optimization

While the target application dictates the RF requirements, efficiency and cost are the main differentiating factors for RF power amplifier solutions. Various techniques can be used to improve efficiency, e.g. technologies such as GaN with increased energy density. Envelope tracking and digital predistortion (DPD) extend the linear range of amplifiers. Classic multipath structures such as Doherty and outphasing amplifiers are experiencing a comeback in current designs.
