The SKY58081-11 Multimode Multiband Tx-Rx Front- End Module (FEM) supports 2G/3G/4G/5G mobile devices and operates efficiently in 3G/4G/5G modes. The SKY58081-11 is part of our Sky5® product portfolio. The FEM consists of 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 low noise amplifier (LNA). Extremely low leakage current maximizes device standby time.
