Digital Attenuator, 31.5 dB, 6-Bit,

TTL Driver, DC - 2 GHz

Features

Description

M/A-COM’s AT-107 is a GaAs FET 6-bit digital attenuator

with a 0.5 dB minimum step size and 31.5 dB total

attenuation. This attenuator and integral TTL driver is in a

hermetically sealed ceramic 24-lead surface mount package.

The AT-107 is ideally suited for use where accuracy, fast

switching, very low power consumption and low

intermodulation products are required. Typical applications

include dynamic range setting in precision receiver circuits

and other gain/leveling control circuits.

screening is available. Contact the factory for information.

Electrical Specifications: T

1. All specifications apply when operated with bias voltages of +5V for Vcc and –5.0V for Vee.

2. This attenuator is guaranteed monotonic.
