Description
M/A-COM’s AT-280 is a 5-bit, 0.5-dB step GaAs
MMIC digital attenuator in a low cost SOIC 16-lead
surface mount plastic package. The AT-280 is
ideally suited for use where high accuracy, fast
switching, very low power consumption and low
intermodulation products are required at a low cost.
Typical applications include radio and cellular
equipment, wireless LANS, GPS equipment and
other gain/level control circuits.
The AT-280 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
