GND
M/A-COM’s MA4VAT2004-1061T is a HMIC PIN
Diode Variable Attenuator which utilizes an
integrated 90 degree 3dB hybrid with a pair of
Silicon PIN Diodes to perform the required attenuation
function as D.C. Voltage (Current) is applied.

This device operates from 0 to 1.66 Volts at 1.50mA
typical control current for maximum attenuation. The
user can add external biasing resistors to the bias
ports for higher voltage requirements as required.
