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 Electrical and Mechanical Specifications The matching circuits are contained within the device. An on-chip Signal pin assignments and functional pin descriptions are active bias circuit is included within the device for both input and described in Table 2. The absolute maximum ratings of the output stages, which provides excellent gain tracking over SKY66293-21 are provided in Table 3. Recommended operating temperature and voltage variations. conditions are specified in Table 4 and electrical specifications are provided in Table 5. The SKY66293-21 is internally matched for maximum output power and efficiency.
