COMPACT ARCHITECTURE FM TRANSMITTERS

• Compact architecture means: the complete FM transmitters is build the in a single chassis and cover all the functions: FM Exciter or Modulator and FM Amplifier.
• The Compact configuration is well suited for low power up to 1 kilowatt or maximum 2 kilowatts.
• Limit power to use compact configuration
• Transmitters in compact configuration over 2KW becomes less reliable and difficult to maintain.
• The weight of a compact transmitter is extremely important because, if too high, there are needed two people to handles it increasing the cost of maintenance on site.

Brief description of the principle of functioning of an FM Exciter-Modulator

The FM Exciter is devoting to take-in the Base Band or Audio Input and to create the RF Signal, with frequency modulation to be transmitted.

The Base Band Inputs are: Mono, Left & Right, Composed MPX .

The base band signal, inside the Modulator, suffer several electronic process to obtain the 75kHz frequency deviation.

In case of stereo, the Left and Right channels are coding to get the composed signal MPX to be transmitted.

Depending on settings Pre-emphasis is applied

Once the base band composite MPX signal is completely process is carried to the VCO to be modulated and converting this amplitude information in frequency modulation information.

The quality of this process have direct impact on the final quality of the sound of the radio.

The last link on the equipment chain, responsible of transmit all the quality of the audio is the FM Modulator.

Each of this process require high precision on the treatment of the signal. For this reason, the broadcaster must choice only Top Quality Professional Broadcast Equipment.

AXON Series of FM Transmitters full fill this requirement.

AIR FILTER AND PCB BOARDS FULLY TROPICALIZED

All our products are equipped with an AIR FILTER mounted on the front panel and easy to clean or replace.

The PCB Boards and the wiring are fully tropicalized by a specific coating for electronic assembly.

Air Filter and Tropicalization provides high protection to the internal components when the equipment is installed on places with dust, humidity, salt and pollution.

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.

Copper Carrier on LDMOS Active components and unbalanced Resistors

active power components such as LDMOS or unbalanced power resistors are mounted on a copper carrier to improve heat dissipation and greatly facilitate maintenance, in fact in cases where LDMOS is mounted directly on the heat sink, it causes high heat sink dissipation and it becomes almost impos­sible to heat the weld.

ALLUMINUM AIR DUCTED 2U CABINET

The equipment is housed into a compact rack mountable 2 Unit Aluminium cabinet.

An exclusive design of the air flow inside the transmitter guide the air into aluminium ducts avoiding contact with the electronic components.

Every component that produces heat is mounted on a heat sink.

Air passes exclusively into the aluminium heat sink avoiding contact with the electronic components.

UNINTERRUPTED SERVICE WITH HARDWARE AND SOFTWARE PROTECTIONS

There are two kinds of protection: Fast Hardware Protection and Soft Software Protections

In some conditions, like a short-circuit on the antenna or coaxial cable, the protection must be hardware and act in few nanoseconds. In fact, the software in this case is not fast enough to grant the protection of the equipment.

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

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

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

The transmitter is protected in case of:

• Load mismatching, antenna short/open circuit.
• Environmental over-temperature
• Cooling failure
• Amplifier breakdown
• Over and Under Voltage DC
• Over and Under Voltage AC
• RF and Power Supply Temperature

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 with 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.

HIGH EFFICIENCY LDMOS TECHNOLOGY UP TO 80% EFFICIENCY CONSTANT AT ANY POWER LEVEL

AXON use Solid State RF power devices, 6th generation LD-MOS High Efficiency and VSWR 65:1 to deliver high reliability and low energy consumption.

The high Efficiency is keep constant at any power level thanks to an intelligent algorithm that control the Voltage Power Amplifier and the Bias to obtain maximum efficiency at any frequency and at any output rated power.

TOTAL SPECTRAL PURITY: > -100 DBC SPURIOUS, > - 84 DBC HARMONICS

The RF module amplifier design and the output filter broad band keeps optimum performances on spectral purity without needing of tuning.

USER FRIENDLY DIRECT KEYS AND LEDs INDICATOR USER INTERFACE

LCD front panel display, Direct Access Keys command and LEDs indicators allows immediate control and visualization of the overall status of the transmitter.

Quick and easy navigation trough menus creates an User Interface friendly, simple and intuitive together an immediate learning, full control and measurements of all working parameter: Output Power Power, Frequency (from 87.5 to 108 MHz), SCAs, Stereo/Mono/MPX, Dynamic Limiter etc.

TOUCH SCREEN BRAIN CONTROL UNIT

The control unit have the specific function to supervise the transmitter, even in case of failure of it (or turned off) manual control of the transmitter guarantee perfect operation.

Weekly scheduler Power Derating

The output power can be programmed depending on time for energy consumption optimization management.
