GaAs IC 4 Bit Digital Attenuator
2 dB LSB Positive Control 0.5–2 GHz
Features
■ Attenuation 2 dB Steps to 30 dB
■ Single Positive Control for Each Bit
■ Low DC Power Consumption
■ Small Low Cost TSSOP-16 Plastic
Description
The AA264-87 is a 4 bit, single positive control GaAs IC
FET digital attenuator in a low cost TSSOP-16 package.
The attenuator requires external 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.
