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 Symetrical as RF Input/Ouput Symetrical as RF Input/Ouput 7 8 Absolute Maximum Ratings @ +25 C 1,2 Parameter Operating Temperature Storage Temperature Junction Temperature RF C.W.
