Description

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 communica-

tion applications requiring variable attenuation in the

824 to 960 MHz bandwidth.
