More than a standalone IP block, Wupatec’s DPD solution is designed to help RF and telecom engineers improve power amplifier linearity while maintaining high output power and efficiency.
Built for demanding digital front-end architectures, the DPD IP Core combines a hardware correction core, signal capture capabilities, and software-driven control to support advanced RF transmitter development.
DPD IP Core
Digital Pre-Distortion for RF Power Amplifier Linearization
The DPD IP Core is designed to compensate for the nonlinear behavior of RF Power Amplifiers in transmitter systems. By applying digital correction before the analog conversion stage, it helps engineers improve Power Amplifier efficiency, maximize output power, and maintain compliant signal distortion levels.
The solution combines a hardware correction core, signal capture, and software-driven control for correction parameter computation and system optimization.
Key Features
FDD & TDD Support
Supports Frequency Division Duplex and Time Division Duplex operation with automatic timeslot detection.
Scalable Hardware Core
Customizable implementation for performance, latency, capture depth, and available DSP/RAM resources.
Signal Capture
Includes signal capture and analysis capabilities to support correction parameter computation and transmitter performance optimization.
Runtime Configuration
DPD model complexity can be configured at runtime to balance linearization performance and update speed.
FPGA & RFSoC Compatibility
Supports major AMD/Xilinx FPGA and RFSoC platforms, including Zynq, UltraScale/UltraScale+ and 7-Series devices.
Software
C API with support for Linux or Bare-metal running on Zynq PS or MicroBlaze soft core processor
DPD performance with 5G NR signals
How does Wupatec’s DPD perform with different power amplifiers? We evaluated it using three RF power amplifiers: Wupatec’s WPA-3342G-55, Ampleon’s BLM10D3438-35AB and NXP’s A3M36SL039.
The measurements used Wupatec’s test setup based on the AMD RFSoC ZCU670 evaluation board. The report shows results with different 5G NR modulated signals and compares each amplifier’s performance without DPD, with Wupatec DPD and with a commercial DPD solution.
Explore the full measurement campaign for the test conditions, graphs and detailed results across all three amplifiers.

OUR SOLUTIONS
Strong digital knowledge that is adaptable and reliable
Wupatec’s two pillars reside in its strong digital and analog knowledge. By having expertise in both fields RF and digital, we ensure DPD friendliness, or the amplifier’s behaviour can be anticipated during the design phase towards its final environment. Let’s work together.
