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. Please refer to Skyworks solder reflow application note, available at www.skyworksinc.com, for instructions on mounting the SKY65112 to a printed circuit board. 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.
1. Case temperature is defined as the temperature of the surface of the exposed paddle where it is soldered to the printed circuit board ground. This surface must be connected via the lowest possible thermal impedance to an adequate heatsink. Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.

CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.
Pin Descriptions Technical Description
The SKY65112 is a single stage linear amplifier. The device should be externally matched for optimum gain and linearity using external passive components on the input and on the output ports. These external components allow the amplifier to be optimized for the desired operating frequency. The RF input is internally connected to pins 2, 3 and 4 via different lengths of bond wire. The inductances produced by these bond wires can be utilized in the impedance matching circuit on the amplifier's input port. The RF output is internally connected to pins 6 and 7 for current sharing. Both of these pins should be connected externally to the same printed circuit board trace. The SKY65112 contains a bias circuit for optimum temperature tracking performance. An external resistor is used to set the bias current level. The value of this resistor can be selected to set the amplifier operational mode to Class A, B, or AB, allowing for optimization of linearity and efficiency.

Evaluation Board
The SKY65112 Evaluation Board is used to test the performance of the SKY65112 power amplifier driver. Schematic diagrams for evaluation circuits, optimized for output third order intercept (OIP3) are shown below. Evaluation board schematics and bills of materials are shown for GSM operation at 940 MHz and also for DCS/UMTS/CDMA operation near 2 GHz. The mounting footprint for the SKY65112 is shown in the mounting footprint schematic. The evaluation board also contains a probe fixture section which makes it possible to conveniently measure scattering parameters with ground-signal-ground probes and a vector network analyzer, directly at the input and output pins of the package. Scattering parameters measured in this fixture are available upon request.
Test Procedure
Use the following procedure to set up the SKY65112 Evaluation Board for testing. Refer to the mounting footprint schematic for guidance: 1. Connect a 5 V supply to VCC. If available, enable the current limiting function of the power supply to 520 mA. 2. Connect a positive supply to VREF. 3. 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. 4. Connect a spectrum analyzer to the RF signal output port. 5. Enable the power supply. 6. Adjust VREF to set supply current (ICCQ) to 260 mA 7. Enable the RF signal. 8. Take measurements.
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 exposed paddle ground pad of the SKY65112 power amplifier has special electrical and thermal grounding requirements. This paddle 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 power produced to the circuit board. Multiple vias to the grounding layer are required.
CAUTION: If any of the input signals exceed the rated maximum values, the SKY65112 Evaluation Board can be permanently damaged.
Recommended Solder Reflow Profiles
Refer to the "Recommended Solder Reflow Profile" Application Note.
Tape and Reel Information
Refer to the "Discrete Devices and IC Switch/Attenuators Tape and Reel Package Orientation" Application Note.
NOTE: Junction temperature (TJ) of the device increases with a poor connection to the exposed paddle and ground. This reduces the lifetime of the device.
3. External bypass capacitors are required on the VCC line and on pins 1. 4. Bias resistors R2 and R4 and the voltage applied to VREF determine the reference current, IREF, into pin 1. This current controls the supply current through the amplifier stage. A suggested matching circuit is shown in the evaluation board schematic.
