RF Power Amplifier and Digital Integration

Synergizing RF Power Amplification and Digital Integration:

In the fast-paced world of radio technology, success depends on mastering both RF power amplifier (PA) design and digital integration. RF power amplifier design ensures efficient and reliable signal transmission, while digital integration harnesses the advantages of digital signal processing, including flexibility, precision, and the integration of advanced features.


At Wupatec, we specialize in combining these two critical aspects to optimize the performance of radio units. This synergy guarantees top-notch transmission quality and adaptability to the dynamic requirements of modern applications, whether in telecommunications, broadcasting, or any other field. We provide an undeniable competitive advantage to professionals in the telecommunications and radio industry, whether updating existing solutions or solving the need of  a custom solution tailored to your unique requirements.

In addition to our standard services, we have the expertise to integrate custom code onto processors within the FPGA of an RFSoC. This ability allows for seamless incorporation of specific functionalities and algorithms into the FPGA fabric, which enhances the performance and versatility of our RFSoC-based solutions. our team ensures smooth integration and optimized resource utilization within the RFSoC platform, whether implementing specialized signal processing algorithms or custom control logic. A power amplifier test platform was designed as an example of our collaborative development effort, and the details are provided below:

Introducing Wupatec's Advanced Test Platform

Wupatec has developed proprietary firmware to accurately characterize RF power amplifiers This firmware is designed to efficiently manage the complex components of RFSoC, making it a highly capable Vector Signal Transceiver or test platform. Wupatec offers its innovative developments as part of a comprehensive measurement service or as dedicated test platforms for amplifier characterization, available on-site at the client’s facility.

Our test platforms are built on the latest RFSoC ZCU670 from AMD and designed specifically for PA characterization. Our test benches are equipped to conduct both Continuous Wave (CW) and Pulsed RF Signal measurements, with configurable pulse rise/fall timings in pulsed mode,. Additionally, they support single or dual-tone measurements and are tailored for 5G modulated signal assessments, enabling precise evaluation of power amplifier linearity performance.

Our platforms utilize the inherent potential of the RFSoC as an integrated Vector Signal Generator (VSG) and Vector Signal Analyzer (VSA) to enable seamless IQ modulation and demodulation. This functionality is supported by the IQSTAR Software from AMCAD, which serves as the driving force behind the entire setup.

In addition, our test benches incorporate closed-loop Crest Factor Reduction (CFR) and Digital Pre-Distortion (DPD) capabilities, leveraging commercial solutions or proprietary DPD and CFR Intellectual Property (IP) developed in-house by Wupatec. This integration ensures comprehensive characterization capabilities, providing our clients with unmatched insights into amplifier performance and behavior.
