Features
Description
M/A-COM’s AT-230 is a 3-bit, 4-dB step GaAs
MMIC digital attenuator in a low cost SOIC 14-
lead surface mount plastic package. The AT-230
is ideally suited for use where high accuracy, fast
switching, very low power consumption and low
intermodulation products are required.
Typical applications include radio and cellular
equipment, wireless LANs, GPS equipment and
other Gain/Level Control circuits.
The AT-230 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process
increased performance and reliability.
