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: * Lower Insertion Loss * Lower distortion through attenuation * Large dynamic range for wide spread spectrum applications 3 4 5 6 7 8 Absolute Maximum Ratings1,2 @ T = +25 C Parameter Operating Temperature Storage Temperature Junction Temperature RF C.W.
