Digital Pre-Distortion (DPD)

Digital Pre-Distortion (DPD)
Power amplifiers with high PAR signals can create non-linearity problems. When a high power signal is applied to the PA input, the PA can't linearly amplify the signal, resulting in a situation leading to gain saturation and distortion, ultimately leading to signal quality degradation, such as worse ACP and EVM. Digtal Pre-distortion (DPD) technology can be used to compensate for the non-linear behavior of the PA. DPD applies “inverse” distortion to the PA inputsignal to cancel the distortion generated by the PA.Enhance power amplifier (PA) development with SystemVue’s DPD Builder

Simplify your power amplifier D&V (Design and Verification) test with N7614B Signal Studio for Power Amplifier Test
With the N7614B power amplifier test software, Signal Studio's performance-optimized test flow --validated by Keysight --enhances the characterization and verification of your devices. Through its application-specific user-interface you'll create a test flow with CFR (Crest Factor Reduction), and/or ET (Envelope Tracking), and/ or DPD (Digital Pre-Distortion) technologies for power amplifier test. For more information, please visit www.keysight.com/find/N7614B

Enhance power amplifier (PA) development with SystemVue's DPD Builder
Prove your amplifier may be linearized with DPD either before building your prototype or after hardware is available. Accelerate implementation of DPD linearization networks, first with a PA model in the virtual world or later with PA hardware and test instruments.
