Tian He, Uma Balaji
2010 PIERS Online  
A Class F power amplifier (PA) at 2.5 GHz has been designed and fabricated. Test results show 15.7 dB gain with 75.75% power added efficiency (PAE ), at an input level of 25 dBm. The design procedure is presented, with various issues illustrated and addressed. A new method is proposed to obtain the optimum load and source impedances without iterations, which would usually be necessary.
