KTX-2012-1000: 1kW PEP MF/HF Transmitter for GMDSS Coast Station
The KTX-2012-1000 transmitter works in the MF/HF frequency range from 1.6 to 30MHz and can deliver up to 1 kilowatt PEP of RF signal into a 50Ω load. The KTX-2012-1000 transmitter uses up-to-date technologies:
- The RF signal is generated by a digital synthesizer with DSP and DDS,
- Use of last generation of MOS-FET solid-state power amplifiers,
has native IP capabilities with the following features:
The KTX-2012-1000 is specially designed to be installed into the maritime coast station fulfilling the GMDSS requirements. It includes one 19" - 32U cabinet (without option), the power supply, the synthesizer, the amplifier and the harmonic filter for an easy installation on site. The main power supply is single phase from 100/240VAC - 50/60Hz.
The KTX-2012-1000 transmitter can be used for Voice, DSC, NAVTEX ( 4 209.5kHz) or other purpose (USB, LSB etc.).
As an option, the KTX-2012-1000 transmitter can control the external KTU-2052-1000 Antenna Tuning Unit (ATU), if the transmitting antenna is not a wide band one.
Other available options are:
- LCD Display for Local Control
- Integrated Matching Box
- Redundancy Switch 2:1
- Tx antenna Matrix
- Tx Antenna Matrix ('M' inputs -> 'N' outputs)
- Local Voice Operator Console with Integrated MF/HF Voice Receiver (KRX-2072)
KTU-2052-1000: 1kW MF/HF ATU for GMDSS Coast Station
The KTU-2052-1000 Automatic Antenna Tuning Unit (ATU) is a professional coupler, which can operate on a whip or a wire antenna configuration in the RF band 1.65MHz to 30MHz to a 50Ω transmitter (the KTX-2012-1000 for instance).
The KTU-2052-1000 is integrated inside an IP65 large plastic resistant to temperature.
The KTU-2052-1000 is connected to the transmitter through a coaxial cable, a power cable and a shielded control cable.
Maximum RF power input is 1000W PEP.
The coupler network configuration is a PI or L type; sensors continually monitor the state of the tuning and relay this information to the processor.
KENTA can also provide the antenna on-demand.
KVHF-4013-50: 50W VHF Transceiver for GMDSS Coast Station
The KVHF-4013-50 transceiver works in the maritime VHF frequency range from 156MHz to 162MHz and can deliver up to 50W of RF signal into a 50Ω load in transmission mode.
The KVHF-4013-50 transceiver uses up-to-date technologies and has native IP capabilities with the following features:
- Control through a high level WEB server (both for settings and monitoring),
High level Monitoring through SNMP (MIB supplied) as an option,
Data input/output both for Voice and DSC fully compliant with the ED137-B standard (VoIP with SIP),
LCD for local settings & monitoring as an option,
Voice accessories for local use (microphones etc.),
The KVHF-4013-50 transceiver is specially designed to be installed into a maritime coast station fulfilling the GMDSS requirements. It fulfill the requirements according to EN 301 929-1 ETSI Standard for stationary sea radio units and guarantee a reliable operation, even in long time stress operation.
The KVHF-4013-50 transceiver is fully integrated inside a 19" - 2U rack with single phase 100/240VAC - 50/60Hz for an easy installation on site.
The KVHF-4013-50 transceiver can be used both for voice (or Phony) and DSC applications (DSC encoders / decoders included, VoIP encoders / decoders included).
Thanks to its experience in maritime communication systems, KENTA can propose turn-key VHF coast stations integrated into a 19'' rack (with antennas, coaxial cables and connectors, duplexers, filters, UPS etc.). Click here for more information.
