Afstudeeropdracht - WO - Elektrotechniek. Design, build and test a compact state of the art High Power Amplifier

Job description

About us

Thales Nederland is active in the Defence and Security sectors and is, with more than 2000 employees, a top provider of high-tech jobs. Product innovation and swift anticipation of the newest technological possibilities are the mainsprings of our business. Examples are radar, communication and command & control systems for naval ships and communication, security and payment systems for trade and industry. Thales Nederland is part of the Thales Group, which has a workforce of 68.000 in more than 50 countries making it one of Europe's largest electronics companies.

Within the Technical Unit RF radar front-ends are developed. This includes antennas, transmitters, signal generators and receivers. Besides product development, innovative technology studies are carried out in this field.

For the transmitters designed and built within TNL it's always a challenge to make the transmitter smaller and increase the output power. Helped by technological progress in the transistor technology, a continuing effort is made to improve the design of High Power Amplifiers (HPA) for our transmitters.

Assignment


Design, build and test a compact state of the art High Power Amplifier

Since the introduction of Gallium Nitride (GaN) transistor technology, new transistors with higher power density for higher frequencies are becoming available on the market. Today these amplifiers are also available in SMT technology and can be used on a PCB.
The complete design process from component selection to measuring prototype hardware will be conducted, combining theoretical and practical work. Novel solutions will be required to meet the challenging specifications.

The assignment is to investigate if discrete transistor HPAs can be integrated into the Thales RADAR transmitters. A complete amplifier design has to be made for a state of the art GaN transistor. This design will involve the selection of a bias point, loadpull simulations, stability considerations and impedance matching. A prototype PCB will be developed and measured and you will finally document your work in a report.
