Radio DAB Transmitters - Digital Audio Broadcasting
Radio DAB Transmitters Extra Efficiency

Supported standards: DAB, DAB+, T-DMB
Excellent MER over 33dB
Very high efficiency
Easy maintenance design
Complete remote control: Web & SNMP
Compatible with all major headend brands

Eurocaster's new radio DAB Transmitter is reaching the highest technology level in both Digital Signal Processing and RF domain.
All models are available also as /XE, eXtreme Efficiency, with overall efficiency up to 42%

Top performances are possible thanks to:

1) Improved digital adaptive precorrection and configuration flexibility
To meet and exceed all the Digital Radio International Broadcasters requirements, optimizing modulation performances in every working condition.

2) High-Efficiency SFK Amplifiers, using latest generation LDMOS devices
more rugged and efficient, special low-loss design of matching and combining system, high-efficiency over 96% power supplies.
Widely reduced overall consumption.

3) Hot pluggable power supplies and RF modules
All RF power modules are hot pluggable (both liquid and air cooled) for an easy and fast maintenance on site. All RF power modules are equipped with hot pluggable independent power supplies for maximum redundancy and easy selection of the operating mode between single phase or balanced three phases.
The latest generation of industry higher class power supplies grants over 96% efficiency with wider input AC range capability and greater ruggedness.

4) Compact-sized amplifier modules thanks to a new concept of heat sync and ultracompact power supplies, both in air or liquid cooling systems.
A 5 kW rms DAB Transmitter in a single rack is just an example of this extreme compactness.

5) Smart System Design
Latest generation RF combiner technology with ultracompact unbalancing dummy loads and a smart intercommunication interface between RF modules, drivers, and Logical Control System.

Main Features
1. Compatible with major headend brands, field-proven
2. Compact, flexible and easy to use in any DAB network
3. High power in extremely compact size and top-level efficiency.
