SKY78191-21 Image

The SkyOne® SKY78191-21 from Skyworks is a Low-band Tx-Rx Front-End Module for 2G/3G/4G mobile devices. It consists of a low-band 3G/4G PA block, low- and high-band 2G PA blocks, a silicon controller containing the MIPI RFFE interface, RF band switches, antenna switches, a bi-directional coupler, and integrated filters for Bands 8, 12, 20 and 26. This FEM is optimized for LTE Advanced, which utilizes Carrier Aggregation for higher data rates. The combined internal filtering, RF matching, and TRx switching optimize performance for popular Downlink (DL) CA band combinations. It contains the necessary components between the antenna and RFIC transceiver and is optimized to provide superior Rx sensitivity and Tx efficiency.

The SKY78191-21 has four auxiliary 3G/4G Tx outputs for external filters and four auxiliary 3G/4G TRx ports to support additional bands. It has an extremely low leakage current that maximizes device standby time. This FEM is available in a package that measures 7.60 x 6.00 x 0.75 mm and the IC die and passive components are mounted on a multi-layer laminate substrate. It is ideal for use in multi-band 2G/3G/4G mobile devices, handsets, data cards, M2M and LTE Advanced Carrier Aggregation (CA) applications.
