The SKY58100-11 from Skyworks is a Low-Band Front-End Module that is designed for 2G/3G/4G/5G applications. It features a 3G/4G/5G PA block, low-band, and high-band 2G PA blocks with a silicon controller containing the MIPI RFFE interface. This module also includes RF band switches, antenna switches, a bi-directional coupler with cascade support, integrated switched duplexer filters, and a low noise amplifier (LNA). It has three auxiliary 3G/4G/5G Tx outputs for external filters and three auxiliary 3G/4G/5G TRx ports to support additional bands. The FEM has an extremely low leakage current which maximizes device standby time.
The SKY58100-11 is optimized for LTE Advanced which utilizes Carrier Aggregation for higher data rates. The combined filtering, RF matching, and TRx switching optimize performance for popular Downlink (DL) CA band combinations in a compact and low-cost solution. It contains all the necessary components between the antenna and RFIC transceiver and is optimized to provide exceptional Rx sensitivity and Tx efficiency. This module has a Skyworks Finger-Based Integrated Power Amplifier Control (FB-iPAC) that minimizes output power variation into mismatch.
The IC die and passive components in this FEM are mounted on a multi-layer laminate substrate. It is available in an SMT package that measures 7.60 x 6.00 x 0.75 mm and is ideal for multi-band 2G 3G/4G/5G mobile devices, handsets, data cards, M2M and LTE Advanced Carrier Aggregation (CA) applications.
