A single-diode compact microwave rectifier with a series band-stop structure is presented in this paper. The bandstop structure is connected to the diode in series to block the harmonics produced ...

Spectral narrowing of a resonant-tunneling-diode (RTD) terahertz oscillator was achieved with phase locked loop system. The oscillator is composed of an RTD, a slot antenna, and a varactor diode for ...
