Description
M/A-COM’s AT-220 is a 4-bit, 2-dB step GaAs MMIC digital attenuator in a low cost SOIC 16-lead surface mount plastic package. The AT-220 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-220 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features
full chip passivation for increased performance and reliability.
