RF Power at HF, VHF and UHF
This session features the latest developments in the production of RF power at frequencies up to 1GHz. The session begins with a survey of transistors for production of 1kW or more of RF power. Next the session addresses operation over wide bandwidths with both ferrite-loaded baluns and continuous-mode operation of an amplifier. Techniques for driving switching-mode power amplifiers and for directly interfacing high-efficiency amplifiers to antennas are described. Finally, the session includes a comparison of EER and Doherty techniques for high-efficiency operation at VHF.
