SKY58105-31

Sky5® Mid and High Band Front-End Module for 3G/4G/5G Applications

Please note: SKY58105-31 is being discontinued and is not recommended for new designs.

The SKY58105-31 Mid/High Band (FEM) supports 3G/ 4G/5G mobile devices and operates efficiently in 3G/ 4G/5G modes. The module has separate 3G/4G/5G PA blocks operating in mid- and high bands, a silicon controller containing the MIPI RFFE interface, RF band switches, MB/HB antenna switches, bi-directional couplers, and integrated filters for Bands 1, 3, 34, 39, 40, and 41. RF I/O ports internally match to 50 ohms, minimizing external components. Extremely low leakage current maximizes device standby time. IC die/passive components are mounted on multi-layer laminate substrate. The module meets 5G NR and LTE advanced requirements where wider bandwidth (100 MHz) and CA are used for higher data rates. Combined filtering, RF matching, and TRx switching internal to the module optimizes performance for Downlink (DL) CA band combinations. The module contains components between antenna and RFIC transceiver and is optimized for superior Rx sensitivity and Tx efficiency.
