Digital Attenuator, 50 dB, 6-Bit,

TTL Driver, DC - 2 GHz

Features

Description

M/A-COM’s AT-106 is a GaAs FET 6-bit digital attenuator

with a 1 dB minimum step size and 50 dB total attenuation.

This attenuator and integral TTL driver is in a hermetically

sealed ceramic 24-lead surface mount package. The AT-

106 is ideally suited for use where accuracy, fast switching,

very low power consumption and low intermodulation

products are required. Typical applications include dy-

namic range setting in precision receiver circuits and other

gain/leveling control circuits. Environmental screening is

available. Contact the factory for information.

Electrical Specifications

(From –55°C to +85°C)

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

2. This attenuator is guaranteed monotonic.

Reference Insertion Loss

Attenuation: 1 dB steps to 50 dB

Temperature Stability: ± 0.18 dB from –55°C to +85°C
