This letter deals with a GaAs MMIC Doherty Power Amplifier (DPA) for X-Band systems. To the best of authors’ knowledge, it represents the first DPA realisation in the X-Band frequency range. Experimental results shown a 30dBm saturated output power and a drain efficiency greater than 53% at 9.5GHz. Moreover, in the 6dB of power back-off (from 18dBm to 24dBm input power), an AM/AM distortion lower than 1dB is also demonstrated with an average efficiency greater than 50%.

Abstract
This letter deals with a GaAs MMIC Doherty Power Amplifier (DPA) for X-Band systems. To the best of authors’ knowledge, it represents the first DPA realisation in the X-Band frequency range. Experimental results shown a 30dBm saturated output power and a drain efficiency greater than 53% at 9.5GHz. Moreover, in the 6dB of power back-off (from 18dBm to 24dBm input power), an AM/AM distortion lower than 1dB is also demonstrated with an average efficiency greater than 50%.| File | Dimensione | Formato | |
