In Fig is shown the connection between Network Analyzer and a Coaxial Filter: with this kind of connection you can measure the Return Loss and the Standing Wave Ratio of the cavity. The frequency Span of the test instrument will be from 5 to 10 MHz. Moving them symmetrically, the return loss change and the frequency will move slowly. The B.W. command allows to set the selectivity of the filter. With the B.W. command extremely open the selectivity will be minimum as the attenuation loss. With the B.W. command closed the selectivity will be maximum as the attenuation loss.
The Coaxial Filter is tuned by move up/down the 2 knobs named “TUNE” for the frequency and rotate the in/out connectors named “LOAD” for the correct Return Loss.
Usually it is better to tune the coaxial filter trying to obtain the best Return Loss inside the wanted band, this is the best way to obtain also a low attenuation between the input and the output port of the filter. If a measure like this is made only using the SWR meter of a transmitter it could be possible to make a big mistake, because the operator could think he optimized the transmission while instead the transmitter is working at the left or right side of the band, so during the modulation it could happen that the SWR increases.
DAB Transmitter
Supported standards: DAB, DAB+, T-DMB
Excellent MER over 33dB
Very high efficiency
Easy maintenance design
Complete remote control (Web & SNMP)
Compatible with all major headend brands
The new radio DAB Transmitters are reaching the highest technology level in both Digital Signal Processing and RF domain.
Top performances are possible thanks to:
Improved digital adaptive precorrection and configuration flexibility
To meet and exceed all the Digital Radio International Broadcasters requirements, optimizing modulation performances in every working condition.
High-Efficiency new SFK Amplifiers Latest generation LDMOS devices
more rugged and efficient, special low-loss design of matching and combining system, high-efficiency power supplies (over 96%). Widely reduced overall consumption.
Hot pluggable power supplies and RF modules
All RF power modules are hot pluggable (both liquid and air cooled) for an easy and fast maintenance on site. All RF power modules are equipped with hot pluggable independent power supplies for maximum redundancy and easy selection of the operating mode between single phase or balanced three phases. The latest generation of industry higher class power supplies grants over 96% efficiency with wider input AC range capability and greater ruggedness.
Compactness Compact-sized amplifier modules thanks to a new concept of heatsync and ultracompact power supplies, both in air or liquid cooling systems. A 5 kW rms DAB Transmitter in a single rack is just an example of this extreme compactness.
Smart System Design
Latest generation RF combiner technology with ultracompact unbalancing dummy loads and a smart intercommunication interface between RF modules, drivers, and Logical Control System.
Phase Locked Loop Programmable
FM Exciter/Transmitter 87.5 – 108 MHz Range
0 – 2500 Watts adjustable power
Now ing have under test the new ” FM Fine Matcher ” to adapt and reduce the SWR in not perfect antenna systems.
