| AT65-0009 Voltage Variable Attenuator 824 - 960 MHz Features * * * * * * 25 dB Attenuation Range High IP3 Excellent Linearity Performance Low Cost/High Performance 50 Ohm Nominal Impedance SOT-25 Package Rev. V3 Functional Diagram and Bias Circuitry GND GND Description M/A-COM's AT65-0009 is an integrated voltage variable attenuator containing two PIN diodes and a passive glass quadrature hybrid. This device is packaged in a 5 leaded SOT plastic surface mount package. Maximum attenuation is typically achieved at 3.5 V bias using the suggested bias circuit. The AT65-0009 is ideally suited for GSM communication applications requiring variable attenuation in the 824 to 960 MHz bandwidth.
