CX65001 8-pin soic tape and reel dimensions evaluation board description skyworks CX65001 evaluation board is used to test the performance of the CX65001 power amplifier driver. the evaluation board schematic diagram is shown in figure 14. the schematic shows the basic design of the board for the 375 to 475 mhz range. figure 15 provides the evaluation board assembly diagram. figure 16 provides the evaluation board layer detail. the mounting footprint for the CX65001 is shown in figure 17. 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 CX65001 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. note : junction temperature (tj) of the device increases with a poor connection to the slug and ground. this reduces the lifetime of the device. 3. external bypass capacitors are required on the vcc line and on pins 4, 5, and 8. 4. bias resistor r1 is used to control the reference voltage of the bias circuit (vcc1) at pin 8. 5. inductor l2 is placed between the bias circuit output (pin 4) and the base of the rf transistor (pin 2) for bias circuit and rf transistor connection. a suggested matching circuit is shown in figure 14. testing procedure use the following procedure to set up the CX65001 evaluation board for testing. refer to figure 18 for guidance: 1. connect a +5.0 v supply voltage 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 C15 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 CX65001 evaluation board can be permanently damaged.
