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 ...

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 ...

LaserMa provides Cr4+:YAG with different doping level. The size could be up to 16×16mm2 with variable length. Initial transmission from 10-92% according to customers’ requirements. Cr4+:YAG Crystal is ...

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.

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 ...

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 ...

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 ...
