Description
Technical Description
The SKY66105-11 contains all of the needed RF matching and DC
biasing circuits. The PA is a two-stage amplifier, capable of over
+30 dBm and optimized for power efficiency. This makes the
device suitable for battery-powered applications where PA power
consumption is of critical importance.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66105-11 are provided
in Table 2. The recommended operating conditions are specified
in Table 3 and electrical specifications are provided in Tables 4
through 6.
The state of the SKY66105-11 is determined by the logic provided
in Table 7. Mode control configurations are noted in Tables 8
and 9.

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 at or below their typical value as provided in Tables 3, 4, and 5. Exceeding any of the limits listed here may result in permanent damage to the device.
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.
