Absolute Maximum Ratings

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.

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.
