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 nominal value. 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.
Technical Description
The matching circuits are contained within the device. An on-chip
active bias circuit is included within the device for both input and
output stages, which provides excellent gain tracking over
temperature and voltage variations.
The SKY66293-21 is internally matched for maximum output
power and efficiency. The input and output stages are
independently supplied using the VCC1, VCC2, and VCC3 supply
lines (pins 16, 14, and 12, respectively). The DC control voltage
that sets the bias is supplied by the VBIAS signal (pin 5).
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 2. The absolute maximum ratings of the
SKY66293-21 are provided in Table 3. Recommended operating
conditions are specified in Table 4 and electrical specifications
are provided in Table 5.
Typical performance characteristics are shown in Figures 3
through 16.
