UMCC offers a wide selection of pin-diode variable attenuators covering frequencies from 10 MHz to 20GHz. 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.

  High Attenuation (BW~67%), 80dB Range, (250MHz - 18GHz in Ranges)
