RF Power Amplifier Design

Wupatec expertise on High Efficiency Power Amplifier for 5G applications

Our RF power amplifier design expertise covers a diverse range of integration levels, offering tailor-made solutions to meet the specific needs of our customers. Our experience allows us to offer solutions ranging from discrete amplifiers to integrated modules or MMICs.

Whether on Class AB or Doherty topologies, single or multi-stage, we offer added value in the design of very wideband RF and instantaneous power amplifiers. Indeed, we have designed amplifiers covering the band from 3.3 GHz to 4.2 GHz and demonstrating an instantaneous linearized band of 600 MHz.

From discrete to integration

Concerning discrete amplifiers, whether you are a designer or user of power bars, we can help you in the design of impedance matching network on printed circuits board such as Rogers 4350 or other, in order to achieve a demonstrator of your technology or a commercial product.

On the integration side, for reasons of compactness, the use of MMIC circuits is widespread in telecom applications, several developments carried out at Wupatec as well as a solid simulation tool base allow us to offer our know-how in the design of MMIC type amplifiers. The solutions can be for example an MMIC chip integrating input matching network up to 50 Ohms, but also output matching network on the same chip if the technology allows it or via another dedicated chip in order to maintain optimal performance.

From Class AB to Doherty

For certain applications, class AB or even C amplifier design can meet the needs. For applications requiring a significant back off power while maintaining a high level of efficiency, Wupatec has extensive experience in the design of Doherty-type power amplifiers.

Over the course of our numerous developments, we have implemented a methodology to ensure the proper functioning of the amplifier designed and also to respond quickly to the feasibility of the requested specifications.

During a multi-stage design we ensure the proper functioning of the entire chain, the interactions of the different stages as well as their stability, thanks to advanced analyzes such as STAN analysis.

From dedicated application to wideband multi applications

There are a multitude of applications requiring power amplifiers, our experience allows us to meet very specific customer needs, whether in terms of RF performance: Gain, Power, Efficiency, Linearity or in terms of compactness.

Thanks to internal developments, we offer very wideband designs making it possible to address various applications with the same amplifier or to meet the growing needs of channel aggregation of 5G signals.

RF power amplifier

Much more than an amplifier design

Our ability to design very wideband power amplifiers is based on 2 other pillars of the company.

On the one hand, measurement and characterization capabilities in order to guarantee functional designs from the first iterations. We can carry out LoadPull characterizations under probes but also connectorized thanks to the creation of test fixtures dedicated to the components.

On the other hand, important digital knowledge, in fact we develop internally the software necessary for the use of RFSoC with the aim of characterizing our broadband amplifiers in a radio unit environment. In addition, we develop our own DPD and CFR algorithms with performances comparable to commercial ones and which can be adjusted to your specific needs.
