Attenuators

UMCC
Solid-State Variable Attenuators
Features: - Frequencies from 10 MHz to 18 GHz - Octave bands to multi-octave bands - Current, Voltage, or Digital Controlled - High accuracy linearized response curves - Fast settling time, low jitter, Low distortion - Temperature compensation, Internal voltage regulation

UMCC offers a wide selection of pin-diode variable attenuators covering frequencies from 10 MHz to 18 GHz. Standard UMCC attenuators are equipped with a linearizer-driver circuitry for attenuation control setting. Control signal is via a voltage or a digital word. Attenuators are also available without a driver where control would be via a forward current or a voltage.

Linearized attenuators are equipped with an advance linearizer-driver circuitry. All control circuits do come with features such as temperature compensation circuitry, regulated supply voltages, and reverse voltage protection. Linearized attenuators can be custom built with a variety of controlling options. Options such as shallower or steeper attenuation slope function, a negative slope function, high resolution D/A converter for fine attenuation step control, and etc.
