UMCC offers a wide selection of
pin-diode variable attenuators covering frequencies from 100 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 driver circuitry
and 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, offset transfer function, high resolution D/A converter for fine
attenuation step control, digital control with latching function
capability, and etc.
