Digital Attenuator, 30 dB, 4-Bit,

DC - 2 GHz

Features

Description

M/A-COM’s AT-232 is a GaAs FET 4-bit digital attenuator

with a 2 dB minimum step size and 30 dB total attenuation.

This attenuator is in a hermetically sealed ceramic 16-lead

surface mount package. The AT-232 is ideally suited for

use where accuracy, fast switching, very low power

consumption and low intermodulation products are

required.

setting in precision receiver circuits and other gain/leveling

control circuits.

Contact the factory for information.

1. All specifications apply when operated with control votlages of 0.0V to -5.0V.

2. This attenuator is guaranteed monotonic.
