Description

M/A-COM’s AT65-0009 is an integrated voltage vari- able attenuator containing two PIN diodes and a passive glass quadrature hy brid. 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.
