MAATCC0013 Voltage Variable Attenuator Rev. V3 824 - 960 MHz Features Functional Diagram and Bias Circuitry 25 dB Attenuation Range High IP3 GND GND Excellent Linearity Performance Low Cost/High Performance 50 Ohm Nominal Impedance Lead-Free SOT-25 Package 100% Matte Tin Plating over Copper Halogen-Free Green Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT65-0009 Description PIN 1 GND PIN 3 M/A-COMs MAATCC0013 is an integrated voltage C5 C6 L1 L2 variable attenuator containing two PIN diodes and a C1 C2 C4 passive glass quadrature hybrid. This device is RF IN C3 RF OUT packaged in a 5 leaded SOT plastic surface mount R1 package. Maximum attenuation is typically achieved V B at 3.5 V bias using the suggested bias circuit. The MAATCC0013 is ideally suited for GSM communica- tion applications requiring variable attenuation in the Pin Configuration 824 to 960 MHz bandwidth.
