Description

The M/A-COM AT-226 is a 4 bit, 1 dB step GaAs MMIC digital attenuator in a low cost TSSOP-16 surface mount plas-tic package. The AT-226 is ideally suited for use where high accuracy, very low power consumption and low inter-modulation products are required. Typical applications include radio, cellular, wireless LANs, GPS equipment and other gain/level control circuits.

The AT-226 is fabricated using mature 1 micron GaAs MESFET process. The process features of AT-226 full chip passivation for increased performance and reliability.
