General 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.
