MACOM’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.
MACOM’s MA4VAT904-1061T PIN Diode Variable
Attenuator is designed for AGC Circuit Applications
• Lower Insertion Loss
• Lower distortion through attenuation
• Larger dynamic range for wide spread spectrum applications
