RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Skyworks Sky5® Front-End Module for Mid- and High-Band 3G, 4G, and 5G Mobile Applications - RF CafeNovember 12, 2020 - Irvine, California - Skyworks is pleased to introduce the SKY58085-11, a Mid- and High Band Front-End Module (FEM) supports 3G / 4G / 5G mobile devices and operates efficiently in 3G / 4G / 5G modes. The module has separate 3G / 4G / 5G PA blocks operating in the mid- and high bands, a silicon controller containing the MIPI® RFFE® interface, RF band switches, MB and HB antenna switches, bi-directional couplers, and integrated filters for Bands 1, 2, 3, 7, 34, 39, 40 and 41. RF I/O ports are internally matched to 50 ohms to minimize the need for external components. Extremely low leakage current maximizes device standby time. IC die and passive components are mounted on a multi-layer laminate substrate. The 62-pad LGA assembly, encapsulated in an 8.6 mm x 6.5 mm x 0.65 mm SMT plastic package, offers a highly manufacturable and low-cost solution.

The SKY58085-11 module is designed to meet stringent 5G NR and LTE advanced requirements where wider bandwidth (100 MHz) and carrier aggregation are utilized for higher data rates. The combined filtering, RF matching, and TRx switching internal to the module optimizes performance for popular Downlink (DL) CA band combinations, all in a compact and low cost solution. The module contains all needed components between the antenna and RFIC transceiver and are optimized for superior Rx sensitivity and Tx efficiency. Two ANT ports provide best flexibility to support multiple ANT configurations and ANT swap function. For the Uplink, the PA blocks support very wide bandwidth 5G NR operations: up to 60 MHz for n1 and up to 100 MHz for n41.

A video demonstration of SKY58085-11 is available on Skyworks' YouTube Channel:
