Application Information
The control FETs that switch fixed attenuator sections into or out
of the main signal path in AA110-85 require negative source
voltage (VCC) for proper operation. The AA110-85 includes an
internal negative voltage generator with a charge pump. The
charge pump oscillator operates at approximately 600 kHz. This
signal and its harmonics can couple into the RF signal path,
which can degrade signal to noise ratio for frequencies less than
approximately 200 MHz. The signal to noise ratio for operation at
frequencies above approximately 200 MHz is not affected.
For applications where the input signal amplitude is less than
-10 dBm and its frequency is less than approximately 200 MHz,
the AA117-85 is recommended. This part is identical to
AA110-85, but with the internal negative voltage generator
circuit disabled. Consequently, an external negative voltage
source is required for proper operation. Please refer to the
data sheet for AA117-85, available at www.skyworksinc.com.

1. Control voltage must not exceed supply voltage.
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.
