Voltage (Current) is applied. 2 GND 3 GND 4 RFin/out Symetrical as RF Input/Ouput 5 RFout/in Symetrical as RF Input/Ouput 6 GND 7 GND 8 DC2 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 Comments Absolute Maximum Ratings @ +25 C Parameter Maximum Ratings Operating Temperature -40 C to +85 C Storage Temperature -65 C to +150 C Junction Temperature +175 C RF C.W. Incident Power +33 dBm C.W. Reversed Current @ -30 V 50nA Control Current 50 mA per Diode Notes: 1. All the above values are at +25 C, unless otherwise noted. 2. Exceeding these limits may cause permanent damage. 1 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
