The AT-118 is ideally suited for applications where linear attenuation and fine tuning are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The AT-118 is fabricated with a mature 1 micron gate length Ga As MESFET process. The process features full chip passivation for increased performance and reliability. 1. 4X 12° 3° 0 .0 3 4 0 .0 1 3 0 .0 0 8 0 .0 4 0 Dimensions are in inches.
