Description
M/A-COM’s AT-260 is a 5-bit, 1-dB step GaAs MMIC
digital attenuator in a low cost SSOP-20 surface
mount plastic package. The AT-260 is ideally suited
for use where high accuracy, fast switching, very low
power
consumption
and
low
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-260 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
