ASTEC UM 1286 UHF modulator, top cover taken off. An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.
A standard-sized 8-pin dual in-line package (DIP) containing a 555 IC.. Integrated circuits and certain other electronic components are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage.
The wide intrinsic region makes the PIN diode an inferior rectifier (one typical function of a diode), but it makes it suitable for attenuators, fast switches, photodetectors, and high-voltage power electronics applications. The PIN photodiode was invented by Jun-Ichi Nishizawa and his colleagues in 1950. It is a semiconductor device.
A Florida family's New Year's Eve celebration turned to tragedy after a 10-year-old girl was struck and killed by a stray bullet from "celebratory gunfire" just moments after ringing in the new ...
Additional to the traditional screw contacts the electrical connection between the module and other parts of the power electronic system can also be achieved by pin contacts (soldered onto a PCB), press-fit contacts pressed into PCB vias, spring contacts that inherently press on contact areas of a PCB or by pure pressure contact where corrosion-proof surface areas are directly pressed together ...
