The SKY58085-11 from Skyworks Solutions is a Mid and High Band Front-End Module (FEM) for 3G, 4G, and 5G applications. This front-end module contains all needed components between the antenna and RFIC transceiver and is optimized for superior Rx sensitivity and Tx efficiency. It has separate 3G / 4G / 5G PA blocks operating in the 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, 2, 3, 7, 34, 39, 40 and 41. The FEM requires a DC supply of 1.8 V and can be controlled via a MIPI RFFE interface.
The combined filtering, RF matching, and Tx/Rx switching internal to the module optimizes performance for popular Downlink (DL) CA band combinations. It has RF I/O ports internally matched to 50 ohms to minimize the need for external components. The FEM supports envelope tracking (ET) operation for EN-DC applications as well as QPSK, 16QAM, 64QAM and 256QAM modulation techniques. It is available in an LGA package that measures 8.6 x 6.5 x 0.65 mm and is ideal for multi-band 3G / 4G / 5G mobile devices, handsets, data cards, M2M and LTE advanced carrier aggregation (CA) applications.
