www.DataSheet4U.com PRODUCT SUMMARY SKY77456 Front-End Module for LTE / EUTRAN Band IV / X (Tx 1710-1770 MHz), (Rx 2110-2170 MHz) Applications Long-Term Evolution (LTE) Evolved Universal Terrestrial Radio Access Network (EUTRAN) Handsets and Data Cards Description The SKY77456 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 SKY77456 meets the stringent spectral linearity requirements of LTE with QPSK/16QAM modulations from 1.4 to 20MHz bandwidth and full or partial resource block allocations with high power added efficiency. The FEM incorporates Inter-Stage Filter and Duplexer, InGaP BiFET PA, and output power detector. Integration of the RF front-end greatly simplifies the design of the 4G-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 FEM achieves low current at maximum output power that significantly reduces the power dissipated in the LTE-enabled handsets or data cards.
