ADVANCE DATA SHEET SKY77185 Power Amplifier Module for WCDMA / HSDPA (1920-1980 MHz) Applications * WCDMA handsets * HSDPA Features * Low voltage positive bias supply - 3.2 V to 4.2 V * Good linearity * High efficiency - 40% @ 26.5 dBm * Large dynamic range * 10-pad package - 3 x 3 x 0.85 mm * Power down control * InGaP * Supports low collector voltage operation * Digital Enable The SKY77185 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient module packs full 1920-1980 MHz bandwidth coverage into a single compact package. Because of high efficiencies attained throughout the entire power range, the SKY77185 delivers unsurpassed talk-time advantages. The SKY77185 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA) data transmission with high power added efficiency. A directional coupler is integrated into the module thus eliminating the need for any external coupler. 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. Output match into a 50-ohm load is realized off-chip within the module package to optimize efficiency and power performance. The SKY77185 PAM is manufactured with Skyworks' InGaP GaAs Heterojunction Bipolar Transistor (HBT) BiFET process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the SKY77185 is supplied directly from any 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. No VREF voltage is required. Power down is accomplished by setting the voltage on VENABLE 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. * No VREF required * CMOS compatible control signals Figure 1.

Typical case markings are illustrated in Figure 7. 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 SKY77185 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, precautions, and handling 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. Figure 6. SKY77185 Pad Names and Configuration (Top View) 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 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 nonfunctional". Skyworks employs most stringent criteria and fails devices as soon as the pad begins to show any degradation on a curve tracer. Figure 7.
