SKY77166 Power Amplifier Module for CDMA2000 (450-460 MHz)
Applications
* Digital cellular (CDMA2000) * Wireless Local Loop (WLL)
Description
The SKY77166 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module developed for Code Division Multiple Access (CDMA2000) handsets and Wireless Local Loop applications. This small and efficient module packs full coverage of the 450-460 MHz bandwidth into a single compact package. The SKY77166 meets the stringent CDMA2000 linearity requirements to and exceeding 29 dBm output power. The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry within the module, which includes onboard bias circuitry as well as input and interstage matching circuits. Output match into a 50-ohm load is realized off-chip within the module package to optimize efficiency and power performance. This device is manufactured with Skyworks' GaAs Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the SKY77166 is supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output in the 3.2 to 4.2 volt range. Power down is accomplished by setting the voltage on the low current reference pin to zero volts. No external supply side switch is needed as typical "off" leakage is a few microamperes with full primary voltage supplied from the battery.
Features
* Low voltage positive bias supply: 3.2 V to 4.2 V * Good linearity * High efficiency across wide dynamic range * Dual-mode operation * 10-pad package: 4 x 4 x 1.15 mm * Power down control * Low power state control * CDMA2000
Skyworks offers lead (Pb)-free, RoHS (European Parliament for the Restriction of Hazardous Substances) -compliant packaging.

procedures recommended by Skyworks, please refer to Skyworks Application Note: PCB Design and SMT Assembly/Rework, Document Number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD-020. Production quantities of this product are shipped in the standard tape-and-reel format. For packaging details, refer to Skyworks Application Note: Tape and Reel Information - RF Modules, Document Number 101568.
Electrostatic Discharge Sensitivity
The SKY77166 is a Class 2 device. Figure 8 lists the Electrostatic Discharge (ESD) immunity level for each non-ground pad of the SKY77166 product. The numbers in Figure 8 specify the ESD threshold level for each pad where the I-V curve between the pad and ground starts to show degradation. The ESD testing was performed in compliance with MIL-STD883E Method 3015.7 using the Human Body Model. If ESD damage threshold magnitude is found to consistently exceed 2000 volts on a given pad, this so is indicated. If ESD damage threshold below 2000 volts is measured for either polarity, numbers are indicated that represent worst case values observed in product characterization. Various failure criteria can be utilized when performing ESD testing. Many vendors employ relaxed ESD failure standards, which fail devices only after "the pad fails the electrical specification limits" or "the pad becomes completely non-functional". Skyworks employs most stringent criteria and fails devices as soon as the pad begins to show any degradation on a curve tracer.

Package and Handling Information
Because of its sensitivity to moisture absorption, this device package is baked and vacuum-packed prior to shipment. Instructions on the shipping container label must be followed regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY77166 is capable of withstanding an MSL3/250 C solder reflow. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 3 C per second; maximum temperature should not exceed 250 C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 250 C for more than 10 seconds.
