Abstract

In this paper we investigate experimentally the effect of the modulation methods on the AM-WIRNA (wide bandpass filter-rectifier-narrow lowpass filter) system. We use two modulation methods: external modulation and direct modulation. Direct modulation is simpler, has a more linear response and requires smaller RF input power as compared to external modulation
