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. 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 SKY67106-306LF is a Class 1B ESD device. Table 3.

Noise Figure vs Frequency Over Temperature Evaluation Board Description Package and Handling Information The SKY67106-306LF Evaluation Board is used to test the performance of the SKY67106-306LF two-stage LNA. An Evaluation Board schematic diagram is provided in Figure 29 (1950 MHz) and Table 5 provides the Evaluation Board Bill of Materials (1950 MHz). 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. An Evaluation Board schematic diagram is provided in Figure 30 (2600 MHz) and Table 6 provides the Evaluation Board Bill of Materials (2600 MHz). THE SKY67106-306LF 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. Evaluation Board assembly drawings are shown in Figure 31 (1950 MHz) and in Figure 32 (2600 MHz). This Evaluation Board has many unused pads for components so that it can accommodate tuning over a wide range of frequencies. Refer to the relevant assembly diagram, schematic, and Bill of Materials for the correct component values and placements for a particular operating frequency. 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. Note that the VDD3 pin on the Evaluation Board does not need to be connected and should be left open. Package Dimensions The PCB layout footprint for the SKY67106-306LF is shown in Figure 33. Typical case markings are noted in Figure 34. Package dimensions for the 16-pin QFN are shown in Figure 35, and tape and reel dimensions are provided in Figure 36.
