AXON

World-class Performance FM TRANSMITTER

Compact architecture

 

The best option for High-End Sound Lovers with the need to broadcast in extreme weather environments

 

AXON guarantees superior quality, reliability and professional features.

 

The Sound Quality of Music and the excellent audio fidelity are the most important features of our AXON transmitter.

With a warm softness of audio, AXON achieves a deep, clean and crystal sound, a very low signal to noise, a very low distortion and a high stereo separation.

 

AXON is the synthesis of robustness, easy maintenance, low energy consumption, Web Remote Control and a Big Sound.

 

AXON takes care of CREATING the FM signal starting from the Audio signal. AXON is the cradle of FM signal modulation.

Protections

There are two kinds of protections: Fast Hardware Protection and Soft Software Protection.

In certain conditions, such as a short-circuit in the antenna or the coaxial cable, the protection must be hardware and it acts in few nanoseconds. The software, in this case, wouldn’t just be fast enough to grant protection of the equipment.

When the fault condition is soft, like an increase of VSWR caused by snow or humidity, a software protection can be used.

On the CORTEX series of FM Transmitters both are implemented: Fast Hardware Protections and Soft Software Protections.

The software protection reduces the output power without on-air interruption, keeping the RF devices always within safe operating parameters.

The transmitter is protected in case of:

  • Environmental over-temperature
  • Cooling failure
  • Amplifier breakdown
  • Over and Under AC Voltage
  • RF and Power Supply Temperature
  • RF Coaxial Output Open or Short Circuit Able of a long working time on Short/Open loads at all phase angles without any damage.
  • Load mismatching, antenna short/open circuit.
  • Capability of a long working time on Short/Open loads at all phase angles without any damage.

 

Beyond the Hardware or Software protection, the transmitter is designed to be rough itself, to keep it functioning perfectly even in the worst case of operating conditions.

To achieve this, the important components of the transmitter are over-dimensioned or hardware protected:

  • 6th generation LD-MOS High Efficiency and VSWR 65:1.
  • Over-dimensioned switching power supply with PFC (Power Factor Corrector).
  • Over-dimensioned Heat Sinks and Fans.
  • Integrated AC Mains filtering.
  • Integrated lightning protection.
  • Integrated overvoltage spikes on the mains protection.

 

Reliability and robustness: designed to be rough in itself

To ensure perfect reliability, all the components are over-dimensioned: heatsinks, fans, dummy loads, LDMOS, power supply.

  • Air filter: it gives high protection to the internal components, mounted on the front panel and easy to clean or replace.
  • Completely made in aluminium: for minimum weight and maximum robustness.
  • The PCB boards and the wiring are fully tropicalized by a specific coating for electronic assembly.
  • These precautions guarantee a long life in extreme environmental conditions, preventing damage due to corrosion and erosion, protecting the components from the inclemency of the tropical climate. Protection from humidity, salt and pollution.
  • Over-dimensioned heatsinks.
  • Over-dimensioned fans.
  • Unbalanced dummy loads are twice the needed quantity.
  • LDMOS RF amplifiers are 30% more powerful than needed.
  • They are 65:1 VSWR tolerant.
  • The power supply delivers 30% more power than the quantity used by the equipment at full rated power.
  • Integrated AC Mains filtering.
  • Integrated lightning protection.
  • Integrated overvoltage spikes on the mains protection.

 

Final test and Burn-in

To get maximum reliability from a transmitter there are no shortcuts: good design, good component quality, and many, really many hours of work and time spent on final test and burn-in.

The final test, together with the "burn-in" are the only key to making a transmitter work well. It is a "sine qua non" condition.

Our engineers are obsessed with taking the final test for as long as possible, checking every detail, not neglecting a single parameter. When the transmitter is finally awarded the "pass" result, it means it works perfectly.

 

Mechanical construction

  • The equipment is housed into a compact 2 Unit Aluminium cabinet rack.
  • Exclusive design of the air flow inside the transmitter guides the air into aluminium ducts, avoiding contact with the electronic components.
  • Every component that produces heat is mounted on a heat sink.
  • The air passes exclusively into the aluminium heat sink avoiding contact with the electronic components.
  • All the cover screws are 5mm in diameter. Typically, 3mm ones are used, but after opening the cover for the first time, some of them will be invariably damaged. A big effort was made to develop the mechanics with big screws, for a greater ease of manipulation of the transmitter when opening and closing the lid, and thus allowing for easy maintenance.
  • The mechanic parts of the transmitter are all made in aluminium. This ensures low weight and robustness.

 

N+1 and Backups systems

  • Conventional standby systems such as exciter standby, (n+1) Transmitter standby, passive standby and active output stage standby can be implemented.
  • No additional control units are needed for the exciter standby and the active amplifier standby.
  • N+1 Profiles connector: it provides 7 different memories selection. Memory settings are located in the internal memory and can be selected remotely or locally.
  • Parallel Remote-Control Connector Interface with dry contact relay outputs and opto-isolated inputs with the following signals available: on/off, local/remote, alarm status, RF higher than a pre-set threshold, reset of alarms.

 

 

Compliant with all the standards: ETSI – CCIR - FCC.

CORTEX meets all the most rigorous electromagnetic quality standards.

 

 

Packing

Shock and vibration during transportation can compromise the result of an installation.

Optimizing the CELL Amplifier dimension and weight allows a small and smart package. Small weight and dimensions help to meet the most demanding transport conditions with: Hermetic temperature vibration control and Shock Isolation, handling light packs, aid the health of the operators.
