Lower Earth Orbit (LEO) satellite constellations are expanding rapidly with continued evolution of 6G based on these developments. As Starlink, OneWeb, and Project Kuiper deploy larger constellations of satellites, and as the transition from 5G-Advanced to 6G millimeter-wave frequencies continues, the demand for effective signal distribution and filtering will be very sharp.

Specifically, LEO satellites require compact, high-reliability components which are capable of operating with the higher frequency bands i.e. Ka, Q and V to allow for more increased data throughout. Beamforming networks are built with precision passive components, as are ground station infrastructure and user terminals.

Sichuan Keenlion Microwave Technology Co., Ltd is such a company based in Chengdu that manufactures microwave components and has more than 20 years of engineering experience. Keenlion provides a range of passive components that fall into category making their product list contain rf filters, power dividers, directional couplers, rf combiners and cavity duplexers, and operate over a frequency range of DC to 50GHz.

Keenlion's 18-40GHz power divider offers the type of performance that is required for applications using satellites and for the upcoming 6G technology. It has very low insertion loss (typically less than or equal to 1.0dB) as well as high isolation from port-to-port (typically greater than 18dB) and can be used for millimeter wave beamforming with phased array antennas and earth stations. Keenlion also offers customizations for the specifications needed in harsh environments with production lead time on standard designs being 3 weeks and 6 weeks for customized designs.

Demand for high-performance passive rf components is expected to stay firm while the market for satellite communications continues to expand.
