Description and Applications
M/A-COM’s MA4VAT907-1061T 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 2.77Volts at 3.0mA
typical control current for maximum attenuation. The
user can add external biasing resistors to the bias
ports for higher voltage requirements as required.
M/A-COM’s MA4VAT907-1061T PIN Diode Variable
Attenuator is designed for AGC Circuit Applications
requiring:
Lower Insertion Loss
Lower distortion through attenuation
Larger dynamic range for wide spread spectrum
applications
