This device operates from 0 to 2 Volts at 330 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 MA4VAT900-1277T 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 7 8 Center Paddle is RF and D.C.
