S-band RF Components

S-band Solutions – Flight-Proven Standard for Space Communications

A complete passive RF ecosystem for secure TM&TC and high-reliability data uplink and downlink.

S-band technology remains the communications backbone for modern space missions, from nanosatellites to larger satellite platforms.
WiRan provides a comprehensive range of flight-proven modules—including diplexers, antennas, couplers, splitters.

Our S-band diplexers enable Full-Duplex communication for Telemetry, Tracking, and Command (TM&TC) alongside payload data transmission using a single antenna. Engineered for extreme RX/TX band isolation, they prevent self-interference and ensure reliable link availability throughout the mission lifecycle.

Key Highlights & Applications:

Flight-Proven Heritage: Modules designed, qualified, and space-tested in collaboration with the European Space Agency (ESA).

Full Coverage (2025–2290 MHz): Ready-to-use frequency allocations eliminating the need for time-consuming custom tuning.
Targeted sub-band coverage eliminating the need for time-consuming custom tuning.

Earth-Orbit Ready Durability: Ruggedized aluminum housing engineered to endure launch shock and extreme thermal vacuum conditions across VLEO, LEO, and MEO.
