Evaluation Board
The SKY73013 Evaluation Board is used to test the performance
of the SKY73013 Direct Quadrature Demodulator. The evaluation
board BOM is as shown in the table below.
The evaluation board for SKY73013 allows the part to be fully
exercised. The board is populated with several components
which are not required for normal operation but facilitate special
testing of the SKY73013, such as two high gain, differential
baseband amplifiers which are well-suited for differential-to-
single-ended conversion, and are included for noise figure
measurements.
The evaluation board requires a power supply voltage of 3.3 V
nominal, that is capable of sourcing 50 mA.

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.
