The SKY58105-11 Mid- and High Band Front-End Module (FEM) supports 3G/4G/5G mobile devices and operates efficiently in 3G/4G/5G modes. The SKY58105-11 is part of our Sky5® product portfolio. 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 and HB antenna switches, bi-directional couplers, and integrated filters for Bands 1, 3, 34, 39, 40, and 41.
RF I/O ports are internally matched to 50 ohms to minimize the need for external components. Extremely low leakage current maximizes device standby time. IC die and passive components are mounted on a 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 popular Downlink (DL) CA band combinations. The module contains necessary components between the antenna and RFIC transceiver and is optimized for superior Rx sensitivity and Tx efficiency. Two ANT ports provide flexibility to support multiple ANT configurations and ANT swap function. For the Uplink, the PA blocks support very wide bandwidth 5G NR operations: up to 60 MHz for n1 and up to 100 MHz for n41.
