Front-End Module for LTE / EUTRAN (Tx 2500-2570 MHz), (Rx 2620-2690 MHz)

The SKY77445 Front-End Module (FEM) is a fully matched, 16-pad surface mount module developed for LTE/EUTRAN applications. Small and efficient, this LTE FEM integrates the interstage filter, input and output matching, power amplifier, power detection, and duplexer into a single 4 mm x 7 mm x 1.1 mm package.

The SKY77445 meets the stringent spectral LTE/EUTRAN requirements up to 23 dBm output power at 3.3 battery voltage. The FEM incorporates Skyworks' BAW Inter-Stage Filter and Duplexer, InGaP BiFET PA, output power detector, and operates down to 2.3 V. Control pads are available to enhance the FEM performance at different power levels.

Integration of the RF front-end SKY77445 greatly simplifies the design of the 3.9G-compatible handset radio or data card as all critical matching between the interstage filter, PA, power detection, and duplexer is optimized within the single module component. By optimizing the efficiency of the InGaP BiFET PA MMIC, reducing RF loss between the integrated components and within the Duplexer itself, and improving the match between the PA and the Duplexer, this FEMSKY77445  achieves low current at maximum output power that significantly reduces the power dissipated in the LTE-enabled handsets or data cards.

This small package uses Skyworks' low cost, multi-laminate substrate technology and is approximately half the size of individually packaged component solutions. The SKY77445 front-end module can save handset and data card designers significant board space and design-cycle time, and significantly simplify supply chain and sourcing of RF components.
