SKY77154

DATA SHEET SKY77154 System Smart® PA Module for CDMA / AMPS (824–849 MHz) Applications • Digital cellular (CDMA) • Analog cellular (AMPS) • Wireless local loop (WLL) Description The SKY77154 System Smart® Power Amplifier Module (PAM) is a fully matched, 8-pin surface mount module developed for Code Division Multiple Access (CDMA) / Advanced Mobile Phone Service (AMPS) and Wireless Local Loop (WLL) applications. This small and efficient module packs a full 824– 849 MHz bandwidth coverage into a single compact package. The device meets the stringent IS95 CDMA linearity requirements to and exceeding 28 dBm output power, and can be driven to levels beyond 31 dBm for high efficiency in FM mode operation. A low current pin (VCONT) provides improved efficiency for the low RF power range of operation. The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC contains on-board bias circuitry, as well as input and interstage matching circuits. The output match is realized off-chip and within the module package to optimize efficiency and power performance into a 50-ohm load. 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 SKY77154 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 • Low VREF - 2.85 V, nominal • Low IREF - less than 1 mA • Good linearity • High efficiency • Large dynamic range • 8-pin package - 3 x 3 x 1.2 mm • Power down control • Dynamic bias control • InGaP • IS95/CDMA2000/EVDO MODULE VCONT (3) MMIC Driver Stage Bias Power Stage Bias Skyworks offers lead (Pb)-free "environmentally friendly" packaging that is RoHS compliant (European Parliament for the Restriction of Hazardous Substances).

VCONT 3 6 GND VREF 4 GROUND PAD (2) 5 GND Electrostatic Discharge Sensitivity The SKY77154 is a Class 2 device. Figure 14 lists the Electrostatic Discharge (ESD) immunity level for each pin of the SKY77154 product. The numbers in Figure 14 specify the ESD threshold level for each pin where the I-V curve between the pin and ground starts to show degradation. The ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body Model. If ESD damage threshold magnitude is found to consistently exceed 2000 volts on a given pin, 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 pin fails the electrical specification limits” or “the pin becomes completely nonfunctional”. Skyworks employs most stringent criteria and fails devices as soon as the pin begins to show any degradation on a curve tracer. Pad layout as seen from top view looking through package.

Typical Case Markings 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 SKY77154 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.
