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
plastic package. The AT-226 is ideally suited for use where
high accuracy, very low power consumption and low
intermodulation 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 full chip
passivation for increased performance and reliability.
