3 Volt Voltage Variable Attenuator

25 dB, DC - 2.5 GHz

Features

• Single Voltage Control: 0 to -3 Volts

• 25 dB Attenuation Range at 0.9 GHz

• Low DC Power Consumption

• SOT-25 Plastic Package

• Tape and Reel Packaging Available

Description

M/A-COM’s AT-255 is a GaAs MMIC voltage

variable absorptive attenuator in a low cost SOT-25

surface

ideally suited for use where variable attenuation, fine

tuning, and very low power consumption are

required.

Typical applications include radio, cellular, GPS

equipment and automatic gain/level control circuits.

The AT-255 is fabricated using a mature 1-micron

GaAs MESFET process. The process features full

chip passivation for increased performance and

reliability.

1. Reference Application Note M513 for reel size information.

2. All sample boards include 5 loose parts.
