SKY77455
Description
The SKY77455 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 SKY77455 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, In Ga P Bi FET PA, and output power detector. Integration of the RF front-end greatly simplifies the design of the 4G-patible handset radio or data card as all critical matching between the interstage filter, PA, power detection, and duplexer is optimized within the single module ponent. By optimizing the efficiency of the In Ga P Bi FET PA MMIC, reducing RF loss between the integrated ponents and within the Duplexer...
