The TX5000A is a high-power, fully solid-state 5 kW MF/HF transmitter designed for continuous-duty operation in critical communication environments such as airport HF ground stations, ATC long-range communication networks, coastal radio facilities and military or governmental communication infrastructures.
Covering the full HF spectrum from 2 to 30 MHz using broadband RF architecture, the transmitter allows instantaneous frequency changes with 1 Hz resolution without mechanical tuning, enabling rapid channel switching and high operational availability.
The system is based on a modular structure composed of a fully digital exciter, multiple solid-state power amplifier modules, RF power combining stages and redundant power distribution units. This modular approach simplifies maintenance, enables fast field replacement of modules and significantly reduces Mean Time To Repair (MTTR).
The TX5000A supports voice and data services including telephony, data transmission and NAVTEX operation. It also includes embedded SELCAL (Selective Calling) with 32-tone capability, allowing selective alerting and automated call initiation in aeronautical HF communication systems, reducing operator workload and continuous monitoring requirements.
Remote operation is supported via Ethernet or RS-232 interfaces, and audio can be provided through standard 600-ohm balanced or unbalanced analog inputs, as well as via VoIP when connected to external ED-137 compatible gateways. This enables seamless integration with modern IP-based Voice Communication Systems (VCS) used in airport and ATC control centers.
Integrated supervision includes built-in wattmeter functions for forward and reflected power as well as SWR monitoring, ensuring safe operation and continuous antenna system supervision. The transmitter tolerates SWR up to 3:1 and supports selectable reduced output power levels to adapt to regulatory or operational requirements.
The equipment is installed in a full-height anticorrosive aluminium cabinet suitable for harsh environmental conditions, including high humidity and coastal or airport outdoor shelters, ensuring long-term reliability in mission-critical installations.
With its broadband RF design, scalable solid-state power architecture, embedded SELCAL capability and VoIP readiness, the TX5000A provides a robust and future-proof HF transmission platform for aviation and other high-availability communication networks.
