High-Power Wideband HF Communications System

FlexRadio’s CLS-9301 combines the proven CL-9300 wideband HF transceiver with the powerful FPA-1K 1-kilowatt amplifier to create a high-performance HF communications system designed for wide-area and global connectivity. Built on an open-architecture SDR foundation, the CLS-9301 delivers exceptional long-range HF performance with clean, low-phase-noise transmission and the flexibility required by emergency management agencies, coastal maritime operators, public-safety networks, and international field operations. Its wideband receive architecture, support for coastal monitoring application and coastal-monitoring applications, and compatibility with SHARES workflows make it a versatile solution for organizations that depend on reliable HF links when other infrastructure is unavailable.

Designed for maximum reach, the CLS-9301 supports resilient networking across distributed sites, including split-site configurations where the transmitter and receiver may be deployed at different locations for improved coverage and reduced interference. With IP-based control, remote monitoring, and broad interoperability with government and commercial HF systems, the CLS-9301 ensures dependable long-haul communications for both planned operations and rapid-response deployments.

With its high output power, modular system design, and proven HF signal quality, the CLS-9301 provides a scalable and future-ready platform for customers who require secure, effective, and far-reaching HF communications under any conditions.

FlexRadio offers the CLS-9300 high-power systems delivering 5 kilowatts of output.
