A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

This report describes the development of low-power balanced diode modulators suitable for amplitude modulation by television or sound signals of a carrier in the frequency range 10-1000 Mc/s. From an ...

If you were asked to name the source most suited to producing femtosecond pulses of light, chances are that you would choose the Ti:sapphire laser. The crystal's thermal properties and its wide ...

This oscillator circuit permits crystals to be electronically switched by logic commands. The circuit is best understood by initially ignoring all crystals. Furthermore, assume that all diodes are ...

Crystal IS, the New York company that is developing novel short-wavelength ultraviolet LEDs, has released the new “Optan” range – said to be the first commercial semiconductors based on native ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

Single excitons in semiconductor microcavities represent a solid state and scalable platform for cavity quantum electrodynamics, potentially enabling an interface between flying (photon) and static ...

The National Space Development Agency of Japan (NASDA) had started some of ground-based research as an initiative to space experiments in a part of the "Space Utilization Research Program" in December ...

Dublin, April 23, 2021 (GLOBE NEWSWIRE) -- The "Global Next-Generation Display Materials Market 2021-2026: Focus on Product Types, Applications and Countries" report has been added to ...
