Description
Skyworks SKY65009 is a high performance, ultra-wideband Power Amplifier (PA) driver with superior output power, linearity, and efficiency. The high linearity and superior Adjacent Channel Power Rejection/Adjacent Channel Leakage Ratio (ACPR/ACLR) performance make the SKY65009 ideal for use in the driver stage of infrastucture transmit chains. The SKY65009 is fabricated with Skyworks high reliability Heterojunction Bipolar Transistor (HBT) process. The device uses low-cost Surface-Mount Technology (SMT) in the form of a 3-pin, 4 x 4 mm Multi-Chip Module (MCM) package (-21 option) or an optional 2.4 x 4.5 mm Small Outline Transistor (SOT) package (-70LF option). The device packages and pinouts are shown in Figures 1 and 2. A functional block diagram is provided in Figure 3.

The SKY65009 is rated to Moisture Sensitivity Level 3 (MSL3) at 250 C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. 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.
Electrostatic Discharge (ESD) Sensitivity 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 SKY65009 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.

Evaluation Board Description
The Skyworks SKY65009 Evaluation Board is used to test the performance of the SKY65009 power amplifier driver. An assembly drawing for the Evaluation Board is shown in Figure 11 and the layer detail is provided in Figure 12. 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 SKY65009 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 13 with component values listed in Table 5 (SKY65009-21) and Table 6 (SKY65009-70LF). Testing Procedure Use the following procedure to set up the SKY65009 Evaluation Board for testing: 1. Connect a 5 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 SKY65009 Evaluation Board can be permanently damaged.
