For this reason, variable attenuators which absorb rather than reflect microwave power are preferred. In order to maximize the range of attenuation (ideally 0-100%), variable attenuators must be capable of absorbing all of the input power. Resistive Film Attenuators. The most common type of waveguide variable attenuator
The X382A waveguide variable attenuator, 8.2 to 12.4 GHz, is designed to be insensitive to temperature and humidity.
4 Nov 2014 Waveguide-based high-frequency systems often require some control of amplitude or signal level. Waveguide attenuators can deliver that means of control, with fixed attenuators providing a single value attenuation setting and variable attenuators providing a range of attenuation control across a desired
Waveguide Variable Attenuators. ATM offers continuously variable attenuators covering the waveguide sizes WR28 through WR284 with variable attenuation from 0-30 dB. Construction includes a multi-turn dial useful for adjusting attenuation, and can be calibrated at a spot frequency upon request. All models have a
WAVEGUIDE VARIABLE ATTENUATOR. WVA Series. 735 West Duarte Road, Suite 401, Arcadia, CA 91007. Phone: (626) 821-9118, Fax: (626) 602-3101, sales@wenteq.com, www.wenteq.com. Key Features. • Full band operation. • Up to 35dB attenuation. • Micrometer re-setting. General Description. Standard WVA
Waveguide variable attenuator suitable for electromechanical control. Abstract: The paper continues research of microwave devices consisting of rectangular waveguide section with dielectric slab in it. The air clearance exists between dielectric slab and wide wall of the waveguide. Variation of the clearance by means of
The VAXE Variable Attenuators are waveguide components for tunable signal leveling or reflection compensation in waveguide networks. The Attenuators consist of waveguide section with a resistive film evaporated on the mica surface. The Attenuators has 0 ?30 dB minimum attenuation range. The VAXE Attenuators are
Millimeter Wave Continuously Variable Waveguide Attenuators. Waveguide Variable Attenuators. 0 - 30 dB attenuation range; Operating frequencies from 33 to 110 GHz in five bands; Low insertion loss from 0.5 to 1 dB. Attenuation adjusted using a built-in micrometer; High quality machining allows consistent performance.
Continuously variable waveguide attenuators from Pasternack are offered in numerous unique models covering a broad frequency range of 33 GHz to 110 GHz in five bands. Pasternack's continuously variable waveguide attenuators can vary the attenuation level from 0 to 30 dB over the specified band allowing the user to
