Description and Applications
M/A-COM’s MA4VAT2000-1277T 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
Voltage (Current) is applied. This device operates
from 0 to 1.5 Volts at 260 uA typical control current
for maximum attenuation. The user can add external
biasing resistors to the bias ports for higher voltage
requirements as required.
