An assembly drawing for the Evaluation Board is shown in Figure 11. A schematic diagram of the SKY65206 Evaluation Board is shown in Figure 12. Step 1: Connect a 3.3 V supply to VCC (see Figure 11). If available, enable the current limiting function of the power supply to 600 mA. Circuit Design Configurations The following design considerations are general in nature and must be followed regardless of final use or configuration: Step 2: Connect a 3.3 V supply to VCTL1, 2, 3, and 4 (these are ports C1, 2, 3, and 4, respectively, on the Evaluation Board). Any unused VCTL pins must be grounded or set to 0 V. Do not float the connections. Step 3: Connect a 3.0 V supply to TX_EN (see Figure 11). 1. Paths to ground should be made as short as possible. Step 4: Connect a digital volt meter to PD_OUT (see Figure 11). 2. The ground pads of the SKY65206-13 have special electrical and thermal grounding requirements. These pads are the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. Therefore, design the connection to the ground pads to dissipate the maximum wattage produced by the circuit board. Step 5: Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of –15 dBm or less to the Evaluation Board but DO NOT enable the RF signal. 3. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. Step 6: Connect a spectrum analyzer to the RF signal output port. CAUTION: Terminate all unused ports in 50 Ω. Step 7: Enable the power supplies. Step 8: Enable the RF signal. Step 9: Take measurements.

Figure 15 provides the package dimensions for the 24-pin MCM and tape and reel dimensions are provided in Figure 16. Package and Handling Information Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. 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. additional information, refer to the Skyworks Application Note, PCB Design & SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. 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. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568. Electrostatic Discharge (ESD) Sensitivity The SKY65206-13 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions. The SKY65206-13 is rated to Moisture Sensitivity Level 3 (MSL3) at 240 °C. It can be used for lead or lead-free soldering.
