Develop a L-band power stage based on European GaN technology with output power in the range of 120-150W capable of power flexibility.

The objective of this activity shall be to investigate very high power amplifiers based on solid state European GaN technology. Unlike the amplifiers available today, GaN technology shall offer the possibility to build such HPA with only one power module at the output. On its own this shall improve efficiency, ease of manufacture and price.This activity shall also investigate the possibility to implement power flexibility and design techniques for increasing efficiency in presence of digitally modulated signals and their implications in case of navigation application (e.g group delay and gain flatness, stability etc..). Finally the activity shall consider careful Multipactor related design.
