PIN 1
M/A-COM’s MAATCC0013 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
MAATCC0013 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.
