Electrical and Mechanical Specifications The absolute maximum ratings of the SKY16406-381LF are Typical performance characteristics of the SKY16406-381LF are provided in Table 2. Electrical specifications are provided in illustrated in Figures 3 through 9. Tables 3. 1 Table 2. SKY16406-381LF Absolute Maximum Ratings Parameter Symbol Min Typ Max Units RF input power, CW RF signal PIN 2.5 W Storage temperature TSTG -65 +25 +150 C Operating temperature TA -55 +25 +105 C 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. 1 Table 3.
