DATA SHEET

AA105-86, AA105-86LF: GaAs IC 4-Bit Digital Attenuator,

1 dB LSB 0.5–3.0 GHz

Features

● Attenuation 1 dB steps to 15 dB with high accuracy

● Single positive control (3 to 5 V) for each bit

● Low DC power consumption

● Miniature, low-cost MSOP-10 plastic package

● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C

per JEDEC J-STD-020

Description

The AA105-86 is a 4-bit, single positive control GaAs IC FET

digital attenuator. It requires DC blocking capacitors, positive

supply voltage (VS) and four individual positive bit control volt-

ages (V1–V4). The AA105-86 is particularly suited where high

attenuation accuracy, low insertion loss and low intermodulation

products are required. Typical applications include cellular radio,

wireless data, and wireless local loop gain level control circuits.

NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances)-compliant packaging.
