HF Class-E based multiplier circuits

In this paper a multiply by five class-E based multiplier circuit with a 32 MHz input signal is described and measurement results, performed on a prototype board, are presented and compared with a classical high frequency simulation tool. Here we don't propose a novel project methodology, but illustrate all the simulation steps and measurements results for an HF class E times five frequency multipliers. The fabricated prototype circuit has 6.77 dB conversion gain at the fifth harmonic with a 29% power added efficiency.
