DATA SHEET SKY77174 Power Amplifier Module for WCDMA / HSDPA (1920–1980 MHz) Applications Description • WCDMA Handsets The SKY77174 Power Amplifier module is a fully matched 10-pad surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient power amplifier packs full coverage of the 1920–1980 MHz bandwidth into a single compact package. The SKY77174 meets the stringent spectral linearity requirements of HSDPA (High Speed Downlink Packet Access) data transmission with high power added efficiency for power output of up to 28 dBm. Because of high efficiencies attained throughout the entire power range, the SKY77174 delivers unsurpassed talk-time advantages. • HSDPA Handsets • Personal Communications Services (PCS) • Wireless local loop (WLL) Features • No VREF required • Low voltage positive bias - 3.1 V to 4.6 V • Supports low collector voltage operation • Good linearity • High efficiency at all power levels (17.5% at 16 dBm) • Large dynamic range • Low Profile package - 4 mm x 4 mm x 1.1 mm • 10-pad configuration The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC includes on-board bias circuitry, as well as input and interstage matching circuits. The output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 Ω load. This device is manufactured with Skyworks’ InGaP 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 SKY77174 is supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output in the 3.1 to 4.6 volt range. No VREF voltage is required. Power down is accomplished by setting the voltage on VENABLE to zero volts. Digital bias control can be used to optimize efficiency at high and low power or analog bias control can be used to optimize efficiency over the entire power range. No external supply side switch is needed as typical “off” leakage is a few microamperes with full primary voltage supplied from the battery. • Power down control • InGaP MODULE • Digital VENABLE • Digital or Analog VCONTROL MMIC VCC2 (10) VCC1 (1) Skyworks offers lead (Pb)-free, RoHS (European Parliament for the Restriction of Hazardous Substances) -compliant packaging.

SKY77174 Pad Names and Configuration The SKY77174 is a Class 1 device. Figure 8 lists the Electrostatic Discharge (ESD) immunity level for each non-ground pad of the SKY77174 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. 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 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. Figure 7. 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 SKY77174 is capable of withstanding an MSL3/260 ° 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 260 °C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 260 °C for more than 10 seconds. For details on attachment techniques, Figure 8. SKY77174 ESD Sensitivity Areas 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 nonfunctional”. Skyworks employs most stringent criteria, fails devices as soon as the pad begins to show any degradation on a curve tracer.
