300W - 600W DAB Radio Transmitters

300W – 600W DAB Radio Transmitters

AIR COOLED DIGITAL COMPACT TX

300W_rms600W_rms

Eletec DAB Radio Transmitters are the state of art for digital signal processing and RF performances. These high-quality parameters are due to:

Digital Adaptive Precorrection (Linear and not linear)

The modulation parameters are optimized for every working condition

9thHV-Generation Doherty LDMOS devices

Only this category of devices merges the high efficiency with an impressive ruggedness

Compact size

High efficiency heat-sinks, very compact power supplies and controlled blowers ensure the highest power density on the market
