AWR, Cree, and Microwave Journal will host a webinar next week. The webcast will help power amplifier (PA) designers learn more about the design of Class F, inverse Class F, and continuous Class F power amplifiers using Cree GaN HEMTs and AWR’s Microwave Office circuit design software. The online seminar will take place Tuesday, March 26 at 11 am EDT. The event is titled: The Design of Class F, Inverse Class F and Continuous Class F Power Amplifiers using Cree GaN HEMTs and AWR’s Microwave Office.
The webcast will focus on the design of power amplifiers employing GaN HEMTs to maximize power added efficiencies by the investigation of optimum source and load-pull at both fundamental and harmonic frequencies. The load-pull scripts that are available in Microwave Office software have been used extensively to find the optimum trade-offs in power gain, efficiency, stability etc.
The webinar will specifically describe the basis of Class F PA design as well as inverse Class F and a relatively new approach called continuous Class F, which enables greater bandwidths to be realized. Several practical design examples will be given including the inspection of voltage and current waveforms for both packaged and bare die transistors in the 10 to 25 watt power range for frequencies up to 2.5 GHz.
