The SKY78188-11 from Skyworks is a Multimode Multiband Tx-Rx Front-End Module that supports 2G / 3G / 4G mobile devices. It has separate 3G/4G PA blocks operating at 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 is optimized for LTE Advanced, where Carrier Aggregation is utilized for higher data rates. The PA blocks support very wide bandwidth operation by intra-band CA up to 40 MHz (200RB) for Bands 1, 2, 3 and 7, and up to 60 MHz (300RB) for Bands 40 and 41. The FEM also supports Downlink/Uplink CA.
The IC die and passive components are mounted on a multi-layer laminate substrate. It is available in a 8.6 mm x 6.5 mm x 0.8 mm, 62-pad LGA, SMT, plastic package and is ideal for Multi-band 2G / 3G / 4G Mobile Devices, LTE Advanced Carrier Aggregation and M2M applications.
