GaAs IC 4 Bit Digital Attenuator

2 dB LSB DC–2 GHz

Features

■ Attenuation in 2 dB Steps to 30 dB

■ Low Cost SOIC-16 Plastic Package

■ Low DC Power Consumption

Description

The AA220-25 is an IC FET digital attenuator consisting

of four monolithic attenuators with LSB of 2 dB and a total

attenuation of 30 dB with all attenuators connected. The

AA220-25 is particularly well suited where high

attenuation accuracy, low insertion loss and low

intermodulation products are required. Typical applications

include cellular, radio, wireless data, wireless local loop

and other gain level control circuits.

Electrical Specifications at 25°C (0, -5 V)

Operating Characteristics at 25°C (0, -5 V)

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

2. DC = 300 kHz.

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

*Due to conflict with another company’s product numbering system, Skyworks’ attenuator products starting with the letters “AD” are being changed to “AA”.
