SKY58813-11

Sky5® Mid- and High-Band Front-End Module for 4G/5G Applications

The SKY58813-11 is an MHB LNA plus Power Amplifier Module with integrated Duplexer (LPAMiD) designed for 4G and 5G mobile devices, supporting operation across mid- and high-band frequencies. The SKY58813-11 is part of our Sky5® product portfolio.

The SKY58813-11 integrates power amplifier (PA) blocks for 4G/5G, a controller with MIPI RFFE interface, RF band switches, MB/HB antenna switches, bi-directional couplers, and filters for Bands 25, 66, and 41.

The module delivers PC1.5 power at 5.5 VCC, offering high performance in a compact form factor. This enables external TX EN-DC for various mid- and high-band combinations and provides primary MHB support for associated applications.

RF I/O ports are matched to 50 Ω, and low leakage current extends standby time. The IC die and passive components are mounted on a multilayer laminate substrate for robust integration.

The module supports 5G NR and LTE, accommodating wider bandwidth and CA for high data rates. Combined filtering, RF matching, and TRX switching enhance downlink CA performance.

MHB and HB antenna ports support multiple antenna profiles, while PA blocks enable uplink operation with wide bandwidth 5G NR (>100 MHz for n41).
