ADVANCE DATA SHEET SKY77435 Front-End Module for WCDMA / HSDPA / HSUPA (Tx 1710-1770 MHz), (Rx 2110-2170 MHz) Applications Description • Digital cellular (WCMDA) handsets The SKY77435 Front-End Module (FEM) is a fully matched, 16-pad surface mount module developed for WCDMA applications. Small and efficient, this WCDMA FEM integrates the interstage filter, the input matching, the power amplifier, the output matching, the power detection, and the duplexer into a single 7 mm x 4 mm x 1.1 mm package. Features • High Speed Downlink Packet Access (HSDPA) • High Speed Uplink Packet Access (HSUPA) • Low quiescent current - 20 mA • Low current consumption - 530 mA • Integrated Power Detector • 16-pad package • Small profile - 7 mm x 4 mm x 1.1 mm • Low voltage - 3.1 V–4.45 V The SKY77435 meets the stringent spectral requirements of HSDPA standards up to 25.2 dBm output power. The FEM incorporates an InGaP HBT PA and contains circuitry to optimize power detector performance. Different control pads are available to enhance the performance of the FEM at different power levels. Integration of the RF front-end greatly simplifies the design of the handset radio as all critical matching between the interstage filter, PA, power detection, and duplexer is optimized within the module. By optimizing the efficiency of the InGaP HBT PA MMIC and reducing the RF loss between the integrated components, this FEM achieves current as low as 450 mA at maximum output power (25.2 dBm) that significantly improves the talk time of the WCDMA handset. This small package uses Skyworks’ low cost, multi-laminate substrate technology and is approximately half the size of individually packaged component solutions. The SKY77435 front-end module can save handset designers significant board space and design-cycle time. • Digital enable pad • Highly integrated, user friendly solution • InGaP HBT • Integrated interstage filter and duplexer • Requires few external components Figure 1.

Figure 7 illustrates typical case markings. The SKY77435 is currently qualified for MSL3/260 °C. 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. Production quantities of this product are shipped in the standard tape-and-reel format.
