Description and Applications
M/A-COM’s MA4VAT904-1061T 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 1.9 Volts at 1.89 mA
typical control current for maximum attenuation. The
user can add external biasing resistors to the bias
ports for higher voltage requirements as required.
