Abstract
Radiation synthesizer systems provide efficient wideband operation with an antenna, such as a loop, which is small relative to operating wavelength. Energy dissipation is substantially reduced by cycling energy back and forth between a high-Q radiator and a storage capacitance under control of a switching circuit. In addition to transmit operation using an energy source such as a battery, by reciprocity receive systems deliver received signals to an output device, such as a speaker or other audio or visual transducer device. By efficient direct processing, via controlled activation of switch devices of switch modules, incident RF signals are converted to baseband signals. Commercial type AM receivers may be provided without IF processing and detection or analog filters.
