1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
ESD HANDLING:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.

BIAS Pin Usage
The SKY66111-11 BIAS pin supplies the bias to the internal PA.
By varying the voltage at this pin, PA operating parameters
including gain, supply current, and efficiency can be adjusted.
The BIAS pin can also be used to adjust the SKY66111-11 output
power when the RF source (transceiver or baseband) has a fixed
level.
