5G NR Conformance Testing

Our company is capable of conducting conformance testing in according with the 5G NR specifications.

These tests include transmitter tests that cover aspects such as the transmit signal quality, the output power dynamics, the Error Vector Magnitude (EVM), Occupied bandwidth emissions, and Adjacent Channel Leakage Ratio (ACLR), among others.

In order to generate test models (NR-TM) in different operating modes and frequency bands, we utilize IQSTAR 5G NR Downlink tools. Our testing methods have been standardized to ensure transmission bandwidth and subcarrier spacing combinations.

Digital Pre-Distortion (DPD) and Crest Factor Reduction (CFR)

Digital Pre-Distortion (DPD) and Crest Factor Reduction (CFR)

Our test benches offer a flexible selection of DPD algorithms, including existing commercial and customized options.

Internal development capabilities enable us to tailor DPD algorithms to specific requirements, such as low latency applications.

Crest Factor Reduction (CFR) techniques, including « Clipping and filtering » algorithms, are integrated into our measurements to optimize power amplifier efficiency.

Time Domain Duplex (TDD) signal measurements

TDD signals alternate between transmitting and receiving within a single frequency band, enabling dynamic resource allocation. This flexibility is pivotal in 5G, optimizing spectrum usage and adapting to changing network needs.

While they offer immense potential, one of the primary challenges is ensuring optimal amplifier performance in demanding TDD environments. This requires a deep understanding of these signals’ characteristics to maximize efficiency.

The image showcases comprehensive measurements conducted with TDD signals (with 1 or 4 carriers of 100 MHz) on our cutting-edge Doherty amplifier, covering the 3.3 to 4.2 GHz band.

Our expertise in mastering the digital pre-distortion (DPD) technology combined with our broadband amplifier enables you to harness the full potential of TDD signals.

Comprehensive Dynamic Reports

After the measurement process, Wupatec uses the tool Whiteboard to view and analyse results.

With this, different sets of small and large signal measurements can be displayed and compared in the same document. Once the desired set of figures is selected, the report can be exported in the desired page format.

This dynamic approach allows real-time display of sweeps in multiple variables, comparison between measurement sets, and an accurate analysis of the results.




Measurement capability that ensures first-pass design success

This provides us with rigorous inputs during the design phase. At Wupatec, we believe this is an essential step to respond to our customers’ needs giving credibility and building confidence. Take a look at our different solutions.
