PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode ...

Whatever happened to the old electromechanical antenna relay? In most modern transceivers it has been replaced by the solid-state antenna changeover switch. However, as a ham-radio hobbyist, I still ...

RF diodes are designed to handle high-power radio frequency (RF) signals in stereo amplifiers, radio transmitters, television monitors, and other RF or microwave devices. PN junction diodes or general ...

Limiters are necessary in situations in which a transmitter delivers signals of peak power on the order of kilowatts or megawatts to an antenna that also connects to the receiver. Receivers, however, ...

Both electromechanical and semiconductor switches are proven technologies used in the control and routing of RF signals. The use of mechanical switches can be justified in precision test equipment, ...

This file type includes high resolution graphics and schematics. Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems. However, ...

LEWISVILLE, Texas – Fairview Microwave Inc. in Lewisville, Texas, is introducing a line of E and W-band RF and microwave PIN diode waveguide switches for radar front ends, telecommunications, test ...

According to a Tyco Electronics application note, “Silver cadmium oxide contacts have long been used for switching loads that produce a high energy arc. Silver cadmium oxide contacts are less ...
