Front-end Module WCDMA/HSDPA

The SKY77437, an efficient FEM developed for WCDMA applications, integrates interstage filtering, input/output matching, power amplification, directional coupling, and duplexing into a single package. The FEM meets stringent spectral requirements of HSDPA standards up to 24.5 dBm output power and includes an InGaP HBT PA with three selectable bias levels to enhance performance at different power levels. Optimizing efficiency of the InGaP HBT PA MMIC and reducing RF loss between integrated components achieves significantly improved talk time. SKY77437 uses Skyworks’ low cost, multi-laminate substrate technology and at approximately half the size of individually packaged component solutions, saves handset designers significant board space and design-cycle time.
