CX65104 8-Pin LCC Tape and Reel Dimensions Evaluation Board Description Skyworks CX65104 Evaluation Board is used to test the performance of the CX65104 PA. The Evaluation Board schematic diagram is shown in Figure 11. The schematic shows the basic design of the board for the 700 to 1000 MHz range. Figure 12 provides the Evaluation Board assembly diagram. Figure 13 provides the Evaluation Board layer detail. Circuit Design Considerations 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 CX65104 PA 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. 3. Two external output bypass capacitors (0.01 µF, and 4.7 µF) are required on the VCC1 (pin 8) supply input. The same three capacitors are also required on the VCC2 (pin 4) supply input. All three capacitors should be placed in parallel between the supply line and ground. See Figure 11 for a detailed diagram. 4. VCC1 (pin 8) and VCC2 (pin 4) may be connected together at the supply. 5. The RF output includes an onboard internal DC blocking capacitor. All impedance matching is provided internally. Therefore, the application only needs to provide a good 50 Ω load. Testing Procedure Use the following procedure to set up the CX65104 Evaluation Board for testing. Refer to Figure 14 for guidance: 1. Connect a +5.0 V supply voltage to VCC1 and VCC2. If available, enable the current limiting function of the power supply to 1.0 A. 2. Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of 3 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. CAUTION: If the input signal exceeds the rated power, the CX65104 Evaluation Board can be permanently damaged. |
