7 Evaluation Board Description The SEL Evaluation Board is used to test the performance of the SEL FEM. The board is optimized for evaluation, experimentation, and investigation with an 80.. signal source. The design and layout can be quickly and easily transferred into a production design. An Evaluation Board schematic diagram is provided in Figure. A reference design schematic is provided in Figure. Table 8 describes the pins on the power and control I/O header (J). Table 9 provides the Bill of Materials (BOM) list for Evaluation Board components. A photograph of the Evaluation Board is shown in Figure. Evaluation Board Setup Procedure. Connect J, J, J, and J to 0 Ω instruments. Terminate all unused ports (if applicable) with 0 Ω.. Connect the supply ground to pins 9 and 0 of J.. Connect.0 V to pins and of J.. Connect.8 V to pins and 8 of J.. Connect.0 V to pins and of J. Package Dimensions The PCB layout footprint for the SEL is provided in Figure. Typical case markings are shown in Figure. Package dimensions for the -pin QFN are shown in Figure 8, and tape and reel dimensions are provided in Figure 9. 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 SEL is rated to Moisture Sensitivity Level (MSL) at 0 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 00. 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: By following the logic in Table, the required RF path is selected. Refer to Tables and 8 for antenna port control.. Monitor the. GHz amplifier transmit performance by applying an RF signal to J and monitoring the output power on J (ANT) or J (ANT). CAUTION: Care should be taken not to overdrive the amplifier by applying too much RF on the input to the device. A suitable starting input power would be 0 dbm.. Monitor the. GHz amplifier receive performance by applying an RF signal to J (ANT) or J (ANT) and monitoring the output signal on J. 09E Skyworks Proprietary Information Products and Product Information are Subject to Change Without Notice March 0, 0
