PCB BOARDS FULLY TROPICALIZED

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 ECO 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

ECO 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.
