D e s c r i p t i o n

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 re q u i red at a low

cost. Typical applications include radio and cellular

equipment, wireless LANS, GPS equipment and other

Gain/Level Control circ u i t s .

The AT-280 is fabricated with a monolithic GaAs MMIC

using a mature 1-micron process. The process features full

chip passivation for increased perf o rmance and re l i a b i l i t y .

1. All measurements at 1 GHz in a 50 system, unless otherwise specified.

2. Attenuation accuracy specifications apply with negative bias control and low inductance grounding.
