GaAs IC 5 Bit Digital Attenuator

1 dB LSB Positive Control 0.5–2.5 GHz

Features

■ Attenuation 1 dB Steps to 31 dB

■ Single Positive Control (+3 to +5 V) for

■ Low DC Power Consumption

■ Small Low Cost SSOP-16 Plastic Package

Description

The AA101-80 is a 5 bit, single positive control GaAs IC

FET digital attenuator in a low cost SSOP-16 package.

This attenuator has an LSB of 1 dB and a total attenuation

of 31 dB. The attenuator requires external DC blocking

capacitors, positive supply voltage (V

bit control voltages (V

suited where high attenuation accuracy, low insertion loss

and low intermodulation products are required. Typical

applications include base station, wireless data, and

wireless local loop gain level control circuits.

Electrical Specifications at -40°C to +85°C (0, +5 V)

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

2. Attenuation referenced to insertion loss.
