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. M/A-COM's MA4VAT2000-1277T 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 1 2 3 4 5 6 7 8 Center Paddle is RF and D.C.
