Why you need a high-power HF transmitter

the Barrett 4075 high-power HF transmitter

When you need to communicate over long distances with confidence and reliability, you need an HF transmitter that can handle the task. With the 4075 high-power HF transmitter, Barrett has risen to the challenge — offering the communications capability you’ve come to expect with a cooling system made for transmitting large volumes of voice and data communications.

The perfect tool for distance communications

The key to the 4075’s success is a marriage of the Barrett 4050 SDR Transceiver with a newly designed liquid-cooled amplifier. This amplifier is available in both 500W and 1KW variants and a first-of-its-kind system that reduces the need for forced air cooling. The results? Top-of-the-line amplification in a small enclosure, with minimum components that extends overall equipment service life.

Coupling these technologies requires no further tuning or adjustment, due to a flexible I/O interface and analogue ALC feedback.

Some of the key features of this device include:

• 1.6 – 30 MHz continuous coverage
• 100% continuous duty cycle at 1kW
• USB, LSB (SSB), CW, FSK and AM Modes
• Remote control via IP and Wi-Fi
• Compatibility with existing four- and six-digit selective calling radio networks
• 2G and 3G Automatic Link Establishment options
• An ARINC ICAO Annex 10 Aeronautical Selcall option
• Field re-programmable USB option

In addition to the capabilities that enable it to communicate over great distances, the 4075 High power HF transmitter has overload protection technology integrated into its system. Intelligent electronic controls can provide early warning signs of either input or output overload, and a diagnostic interface helps with system monitoring and event logging.

Unmatched flexibility and protection

In addition to being ready to handle varied modulating sources like voice and data, the Barrett 4075 can work effectively from nearly any environment in the world. The transmitter is available in a transportable and rugged 9RU 19″ rack mount case.
The system is also field re-programmable via USB, meaning it’s easy to update while in the field.
Wherever a mission may take you, the 4075 high-power HF transmitter is up to the task.
