The SKY78132, SkyOne® Ultra 3.0 is a multimode multiband (MMMB) Front-End Module (FEM) that supports 4G, handsets and and operates efficiently in LTE modes. RF I/O ports internally matched to 50 ohms, minimize the need for external components. Extremely low leakage current maximizes handset standby time. The InGaP/GaAs die and passive components are mounted on a multi-layer laminate substrate and the assembly encapsulated in plastic overmold.

LTE: The SKY78132 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with excellent power-added efficiency.

Receiver Section: The SKY78132’s integrated LNAs, antenna switch and B7 duplexer provide 4G Rx paths from antenna to input ports of RFIC. Optimized low insertion-loss Rx paths, matching circuits, and well-grounded guard traces (high Tx–Rx isolation) inside module mitigate desense problems and enhance sensitivity performance.

LNA Rx Ports: The SKY78132 provides four LNA input ports to support additional bands and MIMO.
