New mmWave designs bring new challenges and attenuator limitations have sparked renewed interest in Faraday rotation ...

Electrical and manual fibre optic variable attenuators are available for a broad range of applications. MEMS, electro-optical, optomechanical versions are available offering ultra-low loss (0.2dB), ...

Variable Optical Attenuators (VOAs) are a key component in fibre optic networks. They allow the optical power to be controlled via a reduction in power out of the device. This can be used in many ...

Truck-mounted attenuators are common today, but back in 1982 when this film was produced, the idea was still novel enough to justify crash-testing potential designs. Hexcell aluminum honeycomb ...

A couple of things the article didn’t mention: 1) Tee attenuators can usually be substituted for Pi attenuators, and the calculating programs I’ve seen will give values for either topology.

Passive Audio Attenuators Jul 24, 2004 12:30 AM, By Chriss Scherer Once in common use in radio, the passive attenuator is used less frequently today because of active circuitry and bridging impedances ...

The high-speed, 11-bit 349-series of PIN diode attenuators covers the 1.0 to 18 GHz range. Operating over octave frequency bands, the digitally controlled attenuators switch in less than 300 ns.
