Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions for the SKY65008 are provided in Table 1. The absolute maximum ratings are provided in Table 2, and the recommended operating conditions in Table 3. Electrical characteristics of the SKY65008 are provided in Table 4. The typical performance of the SKY65008 at various operating frequencies is illustrated in Figures 3 through 9. Package dimensions for the 3-pin MCM are shown in Figure 13, and tape and reel dimensions are shown in Figure 14.
should not exceed 225 C and the time spent at a temperature that exceeds 210 C should be limited to less than 10 seconds. If the part is manually attached, precaution should be taken to ensure that the part is not subjected to a temperature that exceeds 300 C for more than 10 seconds. For details on both 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. Production quantities of both package types for this product are shipped in standard tape and reel formats. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568.
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 SKY65008 can be used for lead or lead-free soldering. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 C per second. Maximum temperature

Evaluation Board Description
The Skyworks SKY65008 Evaluation Board is used to test the performance of the SKY65008 power amplifier driver. An assembly drawing for the Evaluation Board is shown in Figure 10 and the layer detail is provided in Figure 11. Circuit Design Configurations 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 SKY65008 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.
A suggested matching circuit is shown in Figure 12 with component values listed in Table 5. Testing Procedure Use the following procedure to set up the SKY65008 Evaluation Board for testing: 1. Connect a 3.3 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. CAUTION: If any of the output signals exceed the rated maximum values, the SKY65008 Evaluation Board can be permanently damaged.
