There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal values. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

The Evaluation Board is shown in Figure 7. An Evaluation Board schematic is shown in Figure 8. Table 4 provides the Bill of Materials (BOM) for Evaluation Board components. The input and output of the SKY65015-70LF are connected using 50 Ω microstrip transmission lines with DC blocking capacitors, C1 and C2, to the input and output SMA connectors, respectively. The positive supply voltage, VDD, is connected to pin 3 (OUTPUT) of the amplifier using the decoupling network that consists of C4, L1, L2, and R1. The power supply current, IDD, must be limited either by the current limit function of an external bench power supply or by replacing L3 with reistor R1, the value of which is given in shown in Table 5. The Evaluation Board is shipped with L3 in place, which shifts an in-band series resonance of the supply decoupling network out of band. For low frequency applications, R1 may be used to conveniently limit supply current on the Evaluation Board. The Evaluation Board also contains a probe fixture that facilitates the direct measurement of the S-parameters. The probe fixture comprises a very short Co-Planar Waveguide (CPW) transmission line to pin 1 and an identical line to pin 3. The other two pins of the amplifier are grounded. The CPW transmission lines are compatible with ground-signal-ground wafer probe tips, which can be connected to the RF ports of a Vector Network Analyzer (VNA) using coaxial cables. The very small electrical length of these CPW transmission lines obviates the need to de-embed their effects from the S-parameters that are measured. The supply constant current must be applied using the bias tee, which is typically integrated into the VNA, and cascaded with the OUTPUT pin of the amplifier. Package Dimensions Typical case markings for the SKY65015-70LF are shown in Figure 9. The PCB layout footprint for the SKY65015-70LF is provided in Figure 10. Package dimensions for the 4-pin SOT-89 are provided in Figure 11, and tape and reel dimensions are shown in Figure 12. Package and Handling Information Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY65015-70LF is rated to Moisture Sensitivity Level 1 (MSL1) at 260 °C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, Solder Reflow Information, document number 200164. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format.
