Abstract :
In this contribution, the design and full characterisation of a high efficiency ultra-wide-band power amplifier are presented. The amplifier, based on GaN technology device, has been designed using a CAD oriented broad band matching approach for both input and output networks. The continuous wave measurements results in an average drain efficiency around 50% from 0.8 GHz to 4 GHz with an output power higher than 32 dBm in the overall bandwidth.
