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. For details on attachment techniques, precautions, and handling procedures recommended by Skyworks, please refer to Skyworks Application Note, PCB Design and SMT Assembly/ Rework Guidelines for MCM-L Packages, document number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD-020.

B * Skyworks Proprietary Information * Products and Product Information are Subject to Change Without Notice. * July 31, 2006 5 DATA SHEET * SKY65028-70LF Evaluation Board Description The Skyworks SKY65028-70LF Evaluation Board is used to test the performance of the SKY65028-70LF power amplifier driver. The following design considerations are general in nature and must be followed regardless of final use or configuration. 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY65028-70LF power amplifier has special electrical and thermal grounding requirements. This pad is 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 amplifier. As such, design the connection to the ground pad to dissipate the maximum wattage produced to the circuit board. Multiple vias to the grounding layer are required. Evaluation Board Layer Detail Layer 1: Top - Metal NOTE: Junction temperature (TJ) of the device increases with a poor connection to the slug and ground. This reduces the lifetime of the device. Testing Procedure Use the following procedure to set up the SKY65028-70LF Evaluation Board for testing: 1. Connect a 5.0 V supply to VCC. If available, enable the current limiting function of the power supply to 240 mA. 2. 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. Connect a spectrum analyzer to the RF signal output port. 4. Enable the power supply. 5. Enable the RF signal. 6. Take measurements. Layer 2: Ground CAUTION: If any of the output signals exceed the rated maximum values, the SKY65028-70LF evaluation board can be permanently damaged.
