Description
M/A-COM's AT-260 is a 5-bit, 1-dB step GaAs MMIC digi-
tal 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 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-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.
