Keysight Introduces New Method to Accelerate Power Amplifier Digital Pre-Distortion Test Speeds

03/10/2023

Keysight Technologies, Inc. introduces the new Iterative Learning Control (ILC) test method that significantly shortens Digital Pre-Distortion (DPD) test times for power amplifiers.

Power amplifiers (PA) are a core component in wireless communication devices. Characterization of these components is a critical but time-consuming task that can take hours or even days during the research & development (R&D) phase. By shortening the time it takes to complete the design and validation process, power amplifier manufacturers are able to accelerate their time-to-market.

Keysight meets this need by introducing the innovative ILC DPD test method that shortens DPD test time to minutes and accelerates R&D time from test validation to product design and optimization. As a part of Keysight's comprehensive High Frequency Measurement Solution portfolio, the ILC test method runs on the N9055EM0E Power Amplifier Measurement Application and uses the VXG Vector Signal Generator and PXA Signal Analyzer to provide industry-leading test performance for signal generation and analysis.
