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.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
GMIC Circuits are sensitive to electrostatic
discharge (ESD) and can be damaged by static
electricity. Proper ESD control techniques should
be used when handling these devices.
