UHF power amplifier of class E with a series forming circuit

UHF power amplifier of class E with a series forming circuit The E-class mode of a power amplifier with a series (to the switch) forming circuit is investigated. An analysis of such an amplifier model is given. Formulas for the equivalent circuit elements are obtained. The load impedances of its switches on a fundamental frequency and on its harmonics are determined for the considered amplifier and for the device which forms a dual pair with it. The fundamental frequency compensation possibility for the capacitive part on the transistor switch output impedance is demonstrated. With the help of the described approach, the amplifier is developed for a frequency of 915 MHz with a drain efficiency of about 73.2% (PAE is about 71%) and the output power is about 7.32 W. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Microelectronics Springer Journals
