An Evaluation Board schematic diagram (500-2500 MHz) is shown in Figure 8. Evaluation Board assembly diagrams are shown in Figure 9 (2-2500 MHz) and Figure 10 (3200-3500 MHz). Bills of Material (BOMs) are provided in Table 5 (2-500 MHz and 500-2500 MHz) and Table 6 (3200-3500 MHz). 2. Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of 0 dBm to the Evaluation Board but do NOT enable the RF signal. 3. Connect a signal generator to the LOQ signal input port. Set to the desired LO frequency at a power level of 0 dBm, but do not enable. 4. Connect a spectrum analyzer to the IFQ signal output port and terminate the IFI signal input port in 50 Ω. Circuit Design Configurations 5. Enable the power supply. The following design considerations are general in nature and must be followed regardless of final use or configuration. 6. Enable the LO input signal. 1. Paths to ground should be made as short as possible. 8. Take measurements and repeat these steps for channel I. 2. The ground pad of the SKY73001 direct conversion mixer 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 mixer. 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. 3. Two external output bypass capacitors are required on the VCC pins. The values of these capacitors will change with respect to the desired RF frequency. One capacitor should be used for low frequency bypassing and the other capacitor for high frequency bypassing. Special attention should be given so that the smaller value capacitor does not go into selfresonance at the desired RF frequency. 4. Wire wound balanced transformers (baluns) were used during the test and characterization of the SKY73001. Ceramic baluns can be used to create the differential input signals (i.e., RF and LO). However, their performance will limit the overall system performance of the SKY73001. Testing Procedure 7. Enable the RF signal. CAUTION: If any of the input signals exceed the rated maximum values, the SKY73001 Evaluation Board can be permanently damaged. 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. The SKY73001 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 °C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, PCB Design & SMT Assembly/Rework Guidelines for RFLGA Packages, document number 103147. 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. Use the following procedure to set up the SKY73001 Evaluation Board for testing. Refer to Figure 11 for guidance: 1. Connect a +3.0 VDC power supply using an insulated supply cable. If available, enable the current limiting function of the power supply to 100 mA. Electrostatic Discharge (ESD) Sensitivity The SKY73001 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
