TECHNOLOGIES

GRF

GreenRF technology is the evolution of the COLD-FET technology adopted by DB for its transmitters. With the use of special high performance LDMOS transistors, this technology brings innumerable advantages, among which a high RF efficiency (> 70%), high reliability and safety, less heating and AC power consumption, which lead to a very longer transmission life.

ACS

Automatic Current Sharing technology consists of an automatic current balancing system and a perfect load distribution, creating optimal power operating conditions that lead to maximum redundancy. As a result, the output power loss in the event of a power failure is extremely low and, in a dual power supply configuration, the power loss in the event of a power unit failure is less than 35%.

Only on models from 2000W and up.

APS

Anodized Protection System, is a special treatment applied to the surface of the aluminium body of the transmitters and to some of its components, preventing corrosion due to humidity or sudden changes in temperature and increasing reliability and longevity.

HSS

With the Hot Swap System present in the transmitters it is possible to carry out maintenance on the power supplies with the machine on and on the air in less than 5 minutes as well as for the amplifiers in modular transmitters. Even the cooling fans can be removed, cleaned or replaced in just 5 minutes thanks to their placement outside the machine.

RCS

Responsive Cooling System is an optimized and highly efficient cooling system. Thanks to the ability to react to changes in temperature of the transmitter or the environment, the system guarantees correct operation and optimal performance even in extreme climatic conditions or in the presence of high temperatures. The cooling system keeps the heat sink temperature at optimum levels.

AIR

The DB air cooling system not only prevents the device from overheating but extends the life of the transistors by far. In the transmitters and amplifiers the fans are mounted externally to allow easy and quick cleaning, or possible replacement, without opening or removing any module and without interrupting the operation of the transmitter.

LIQUID

An oversized heat exchanger, single or double (optional), suitable for outdoor or indoor installation, and equipped with single or double pumping system (optional) for maximum redundancy, is the main component of DB's powerful liquid cooling system. Thanks to the special design of the liquid cooled heat sinks inside the amplifier and the low pressure liquid distribution, this system ensures high reliability, cooling efficiency and ease of installation. Compared to the air cooling system, the liquid cooling system brings several advantages, such as:

  1. Correct operation even in extreme climatic conditions
  2. Significant reduction in the amount of air conditioning required
  3. Correct operation in dusty environments, with high humidity or salinity
  4. Very low acoustic noise
  5. Low thermal dispersion in the environment
  6. Longer life of transistors and active components thanks to their continuous operation at lower temperatures.

WEB

Extremely detailed and intuitive web interface with all main parameters fully controllable and adjustable. Ability to remotely check the status of the transmitter and set malfunction alerts via e-mail and/or trap for prompt intervention. Firmware that can also be updated remotely and an easy back-up system for personal data and configuration.

N+1

The N+1 logic control units reduce the need for multiple backup transmitters by ensuring automatic switching in the event of a failure and automatic loading of the faulty transmitter configuration onto the spare one for a system always at full power.

SMART DESIGN

Thanks to its research and development center, DB is constantly working to improve the design of its products so that the interaction between user and devices is always easier, more intuitive and maintenance faster and cheaper. The clever placement with direct access of the fans in the back and outside of the transmitters and amplifiers and that of the power units with easy access are the result. Such as the combination of latest generation RF combiner technology with ultracompact unbalancing dummy loads and a smart intercommunication interface between RF modules, drivers, and Logical Control System.
