Abstract
A compact configuration of a 2.45-GHz microwave to dc power conversion circuit realizing a class-F operation is proposed. In the ideal class-F operation, harmonic power dissipations are eliminated by open and short terminations for the odd and the even harmonics, respectively. The proposed antisymmetric configuration of two single-shunt-diode rectifiers do not need explicit filters for the even harmonics. A design example that contains an impedance matching network at the fundamental frequency and a third-harmonic rejection filter is presented. Simulation results show that it also realizes approximately short terminations for the second and the fourth harmonics. A fabricated circuit achieved 77.9% RF-dc conversion efficiency when 27-dBm power of 2.45-GHz microwave was supplied.Keywords
