GaAs IC 5 Bit Digital Attenuator With

Serial-to-Parallel Driver 0.5–2.5 GHz

Features

■ Positive Voltage Operation (+5 V)

■ MLF 5 x 5 mm Leadless Package

■ Integrated Silicon Serial-to-Parallel Driver

■ Attenuation 1 dB Steps to 31 dB

Description

The AA109-310 is a GaAs FET IC 5 bit digital attenuator

with a serial-to-parallel driver packaged in a 32 leadless

exposed pad plastic package. It is particularly suited where

high attenuation accuracy, low insertion loss and low

intermodulation products are required.Typical applications

include base station, wireless and wireless local loop gain

control circuits.

Electrical Specifications at 25°C (V

DC Electrical Characteristics at 25°C (0, +5 V)

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

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

3. Attenuation value referenced above insertion loss.
