ADVANCE DATA SHEET SKY77425 Front-End Module for CDMA (Tx 824-849 MHz), (Rx 869-894 MHz) Applications Description • Digital cellular (CMDA) handsets The SKY77425 Front-End Module (FEM) is a fully matched, 20-pad surface mount module developed for CDMA applications. Small and efficient, this CDMA FEM integrates the interstage filter, the input matching, the power amplifier, the output matching, the directional coupler, and the duplexer into a single 4 mm x 7 mm x 1.1 mm package. • Wireless Local Loop (WLL) Features • Low quiescent current - 10 mA Low Mode • Low current consumption - 500 mA @ 26.0 dBm • Integrated Coupler • 20-pad package • Small profile - 4 mm x 7 mm x 1.1 mm • Low voltage - 3.2 V to 4.2 V • Digital enable pad The SKY77425 meets the stringent spectral requirements of IS95/I98 standards up to 26.0 dBm output power. The FEM includes an InGaP HBT PA incorporating three selectable bias levels 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, directional coupler, 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 500 mA at maximum output power (26.0 dBm) that significantly improves the talk time of the CDMA handset. This small package uses Skyworks’ low cost, multi-laminate substrate technology and is approximately half the size of individually packaged component solutions. The SKY77425 front-end module can save handset designers significant board space and design-cycle time. • Highly integrated, user friendly solution • InGaP HBT • Integrated interstage filter and duplexer • Requires few external components Figure 1.
