Abstract
Simple class F with medium output power at 433 MHz is designed and simulated in this paper. The design process uses fundamental frequency tuning in find the matching network. At fundamental frequency, the reactance part of the networks needs to be conjugate values of that of the output impedance of the transistor circuit while the resistance part of the network is found by running simulation sweep. The second and third harmonics are also considered in the matching network design. Using the designed matching networks, the amplifiers yield almost optimum efficiency values for input power of 13 and 18 dBm. The proposed technique can save computational costs comparing to load pull technique. In future work it can lead to implementation of a class F power amplifier without using load pull.
