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. M/A-COM’s MA4VAT904-1061T 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
