Lowest dimensions and weight in the industry. Thanks to the new coupling architecture it has been possible to realize a dramatic reduction of dimensions, weight and cooling, thus simplifying transport, installation and maintenance operation at the same time.

Cold Fet™ technology. This revolutionary technology, a ITEL International patent, is used in the FA 5000FS M2.5 amplifier to optimize the input matching of MOS-FET transistors in order to obtain broadband amplification stages without any RF component. This means:
high RF efficiency > 83%
lower heating
higher devices safety
higher total reliability
low AC power consumption

Extraordinary RF efficiency: the COLD-FET™ technology allows to obtain from the amplifiers the full power rating reducing of almost 20% the devices recommended operating DC voltage and current.

Uninterrupted service. A proportional foldback protection circuit reduces the output power without any on-air interruption, keeping the RF devices always within the safety conditions in case of:
load mismatching
environmental over-temperature
cooling failure
failure in one or more RF stage
failure in power supply modules

Modules redundancy: The FA 5000FS M2.5 amplifier is composed of 18 x 300 W stages coupled with high isolation combiners. This architecture assures the highest module redundancy.

High gain 20 dB gain permits the full output power with low input driving.

Broadband: no adjustments are required for the full power operation in the 87.5÷108 MHz band.

The automatic power control circuit adjusts and stabilizes with precision (±1%) the maximum output power in the whole band.

The switch-mode power supply is largely oversized and guarantees a regular operation even in the presence of wide main voltage fluctuations: the switching converters contribute to obtain a very high AC to RF efficiency (67% typ.).

Low overheating. The high cooling system efficiency limits at only + 10°C the heatsink overheating respect to the environmental temperature. This permits the service even in overheated sites.

Low consumption. The high overall efficiency means a reduction of AC power consumption and operating costs.

Reduced maintenance. Easy accessibility of all parts, no RF failure, no power supply failure, external serviceable air filter reduce dramatically the maintenance costs.

A digital meter combined with LED indicators allows the user to check all the most important parameters of the equipment. The measures are visualized directly on the digital LCD display.

Remote control. It is available as option a remote control interface for the following parameters: voltages and currents of each RF stage, forward power, reflected power, alarms status, on/off, stand-by.
