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 ...

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

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.

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC … ...

The attenuators come already fine-tuned to meet performance specifications, eliminating any fine-tuning, or reworking that would have to be done by the customer. The devices offer the following ...

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.

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 ...
