The SKY58081-11 from Skyworks is a Multi-Band Tx-Rx Front-End Module (FEM) that supports 2G/3G/4G/5G mobile devices. It is optimized for LTE Advanced which utilizes Carrier Aggregation for higher data rates. The module integrates a low-band 3G/4G/5G PA block, low band, and high-band 2G PA blocks, a silicon controller containing the MIPI RFFE interface, RF band switches, antenna switches, a bi-directional coupler, integrated filters for Bands 8, 12, 20 and 26, and a low noise amplifier (LNA). It has four auxiliary 3G/4G/5G Tx outputs for external filters and four auxiliary 3G/4G/5G TRx ports to support additional bands.
The FEM contains necessary components between the antenna and RFIC transceiver and is optimized to provide superior Rx sensitivity and Tx efficiency. It has linear-GMSK, VRAMP, EDGE linear modes which make it a very versatile module. The module’s RF coexistence planning and system techniques are employed to efficiently minimize Rx de-sensitizing. It features MIPI® RFFE 3.0 control interface with a 1.8 V nominal supply.
The FEM is available in a 56-pad MCM package that measures 7.6 x 6.0 x 0.7 mm and is suitable for multi-band 2G 3G/4G/5G mobile devices, handsets, data cards, M2M, and LTE Advanced Carrier Aggregation (CA) applications.
