SKY77806 Multiband Front-End Module for LTE Bands 12 / 17, 13
Applications
Multiband 2G, 3G/4G handsets - LTE-modulated handsets for Bands 12 / 17, 13
Description
The SKY77806, a multiband LTE Front-End Module (FEM), efficiently supports 4G handset operation. The FEM consists of a PA block, a logic control block for multiple power control levels, band enable functions, and integrated duplex filters with single-ended receive outputs. The 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 silver plated plastic overmold. LTE: SKY77806 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 10 MHz bandwidth, including various resource block allocations, with good power-added efficiency. Receiver Section: The SKY77806’s integrated Duplexers provide 4G Rx paths from antenna to LNA port of RFIC. Carrier Aggregation (CA) requirements for noise and harmonics are designed-in for best de-sense performance. Additionally, GPS and LB/HB WiFi coexistence are designed-in for exceptional support to maintain all radio performance, even in user scenarios of simultaneous use. Optimized low insertion-loss Rx paths, matching circuits, and well-grounded guard traces (high Tx–Rx isolation) inside the module mitigate de-sense problems and enha...
