How to Develop and Verify Digital Predistortion Workflows

Develop Digital Predistortion Verification

Transmitter teams need a practical way to build and validate digital predistortion workflows as bandwidth, output power, and linearity demands continue to rise. Multiband vector transceiver solutions provide repeatable wideband RF measurements to characterize distortion, compare pre- and post-correction behavior, verify linearization effectiveness, and correlate results across development, design verification, and manufacturing.

A compact PCI extensions for Instrumentation (PXI)-based architecture supports non-signaling frequency range 1 (FR1) and high-intermediate frequency (IF) measurements in two- or four-channel configurations with up to 1.2 GHz bandwidth and timed multiple-input multiple-output (MIMO). Engineers can capture transmitter behavior before and after predistortion, compare spectral regrowth, and verify digital predistortion (DPD) linearity.

Digital Predistortion Workflow Solution

Multiband vector transceiver solutions support digital predistortion workflow development and verification with a compact, scalable MIMO test approach for wideband transmitter characterization. By combining repeatable signal generation and analysis with RF measurements used to observe spectral regrowth and modulation behavior, engineers can evaluate whether predistortion is improving linearity as intended. A common software environment helps streamline movement from algorithm development to hardware verification, while flexible multichannel architecture supports efficient correlation across validation stages. This approach helps teams troubleshoot faster, improve confidence in linearization results, and reduce effort when validating multiband transmitter performance before release.
