Description and Applications

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.

M/A-COM’s MA4VAT2004-1061T PIN Diode Variable Attenuator is designed for AGC Circuit Applications requiring:
