GaAs IC 1 Bit Digital Attenuator

10 dB LSB DC–2.5 GHz

Features

■ Attenuation Cutback of 10 dB

■ Single Positive 3 V Control

■ Low Loss

■ Low Cost SOT-5 Plastic Package

Description

The AA103-72 is a 1 bit GaAs IC FET digital attenuator

in a low cost package. This attenuator has an LSB of

10 dB. The AA103-72 is particularly suited where high

attenuation accuracy, low insertion loss and low

intermodulation products are required. Typical applications

include cellular radio, wireless data, and wireless local loop

gain level control circuits.

Electrical Specifications at 25°C (0, +3 V)

Operating Characteristics at 25°C (0, +3 V)

1. All measurements made in a 50 Ω system, unless otherwise specified.

2. Insertion loss changes by 0.003 dB/°C.

3. Maximum attenuation includes insertion loss.

4. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.

5. Switching characteristics will vary with value chosen for C
