0.5 dB LSB Positive Control 0.5–2.0 GHz
DATA SHEET
Features
Attenuation 0.5 dB steps to 15.5 dB with high accuracy
Single positive control (3 to 5 V) for each bit

Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C
per JEDEC J-STD-020
Description
The AA106-86 is a 5-bit, single positive control GaAs IC FET dig-
ital attenuator in a low-cost MSOP-10 package. This attenuator
has an LSB of 0.5 dB and a total attenuation of 15.5 dB. The
attenuator requires external DC blocking capacitors, positive
supply voltage (VS) and five individual bit control voltages (V1–V5).
The AA106-86 is particularly suited where high attenuation accu-
racy, low insertion loss and low intermodulation products are
required. Typical applications include cellular radio, wireless data,
and wireless local loop gain level control circuits.

Pin Out
DC blocking capacitors (CBL) and biasing resistor must be supplied externally for positive
voltage operation.
CBL = 47 pF for operation >500 MHz.
1. All measurements made in a 50 system, unless otherwise specified.
2. Insertion loss changes by 0.003 dB/°C.
3. Attenuation referenced to insertion loss.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
