MA4VAT904-1061T High IIP3 PIN Diode Variable Attenuator 0.8 - 1.0 GHz Rev. V4 Features 1.0 dB Insertion Loss, Typical 12 dB Return Loss, Typical 25 dB Attenuation, Typical 45 dBm IIP3, Typical ( 1MHz Offset, @ +0dBm Pinc ) SOIC-8 Surface Mount Package RoHs Compliant Extra Features Covers the following Bands: GSM AMPS Usable Bandwidth: 0.60 GHz to 1.20 GHz 1.5 dB Insertion Loss, Typical 1.8:1 VSWR, Typical 18.5 dB Attenuation, Typical Description and Applications M/A-COM's MA4VAT904-1061T is a HMIC PIN Diode Variable Attenuator which utilizes an integrated 90 degree 3dB hybrid with a pair of Silicon PIN Diodes to perform the required attenuation function as D.C. 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 SOIC-8 PIN Configuration (Topview) PIN Function Comments 1 DC1 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 Absolute Maximum Ratings @ +25 C 1,2 Parameter Maximum Ratings Operating Temperature -40 C to +85 C Storage Temperature -65 C to +150 C Junction Temperature +175 C RF C.W.
