SKY5A3058

Sky5® Low Band TX-RX Front-End Module for 3G/4G/5G Applications with Low Band/High Band 2G

The SKY5A3058 Sky5® TX/RX Front-End Module (FEM) supports 2G/3G/4G/5G for automotive and telematics NAD. 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, 26, 28A, and 29, and LNA. Extremely low leakage current maximizes device standby time. The SKY5A3058 is part of our Sky5 product portfolio.

The IC die and passive components are mounted on a multi-layer laminate substrate. The assembly allows a highly manufacturable, low cost solution.

The device is optimized for LTE Advanced which uses CA for higher data rates. The combined filtering, RF matching, and TRX switching internal to the FEM optimizes performance for popular DL CA band combinations in a compact and low-cost solution. The FEM contains the necessary components between the antenna and RFIC transceiver and is optimized to provide superior RX sensitivity and TX efficiency.

Selecting the linear-GMSK operation standard disables VRAMP input, so all PA biasing depends only on MIPI mode selection. The transmitted envelope is then a linear function of RF input. Selecting VRAMP-enabled operation, the PA controller provides VRAMP control of the GMSK envelope and reduces sensitivity to input drive, temperature, power supply, and process variations.
