Bruco Integrated Circuits is a fabless design center focusing on RF IC and Analog/Mixed-signal IC design and RF Power Amplifier application design. We provide design services and turn-key solutions from early system specification to qualified silicon and take care of the supply chain during product lifetime.

Hands-on GaN Doherty amplifier design

Although we have been developing RF power amplifiers for more than a decade, it does not grow old and the challenges remain. This talk will take you through the paces of a Doherty amplifier development process with all its pitfalls and hurdles. Using newly developed GaN devices as example, the flow will be illustrated step by step, sharing experiences in designing these amplifiers for 5G basestation applications in the 3.5 GHz band.

 

The speaker, Martijn Brethouwer is a senior RF application engineer at Bruco Integrated Circuits. He has more than four years of experience in developing Doherty amplifiers. Before joining Bruco IC, he worked two years at Astron as an RF engineer. He holds an MSc degree in electrical engineering from the University of Twente.
