Abstract

In this contribution a C-Band 2nd harmonic tuned hybrid power amplifier utilizing a PHEMT GaN device is presented,together with technological aspects, non linear device model and adopted design criteria. The amplifier has been realised in hybrid form, exhibiting a bandwidth larger than 20% around 5.5GHz, with a minimum output power of 33 dBm, and a drain efficiency of 60% at the centre frequency.
