GaAs IC 4 Bit Digital Attenuator

1 dB LSB Positive Control 0.5–2.5 GHz

Features

■ Attenuation 1 dB Steps to 15 dB

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

■ Low DC Power Consumption

■ Small Low Cost TSSOP-16 Plastic

Description

The AA226-87 is a 4 bit, single positive control GaAs IC

FET digital attenuator. It requires DC blocking capacitors,

positive supply voltage (V

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 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.
