CODAN 5900 series Ku Band VSAT satellite transceivers offer a wide range of distinctive advantages and enhanced features for satellite communications systems based in remote or challenging geographic regions.
Available in all common VSAT Ku-Band operating frequencies and 70 or 140 MHz IF configurations-and a range of power outputs-the CODAN 5900 provides industry leading technical performance.
Key features
Durability
The CODAN 5900 series VSAT transceiver is designed and tested to meet its performance specifications in an ambient temperature range from -40°C to +55°C and up to 100% relative humidity, ensuring long-term survival in extreme conditions.
The thermal protection provided allows operation up to +60°C ambient. Field experience shows that MTBF of greater than 100,000 hours can be expected.
RF performance
RF performance is superb, particularly: intermodulation performance, gain stability over temperature and flatness across the IF band.
The CODAN 5900 VSAT transceiver also boasts industry leading spurious and harmonics specifications while guaranteed RF performance ensures expensive system link margins do not have to be used to cope with RF transceiver variations. The CODAN 5900 VSAT transceivers high linearity and low spurious characteristics contribute to superior multi-carrier performance.
Output power options
Output ratings of 4, 8, and 16 watts are standard, while a higher power option is also available.
The 8 and 16 watt VSAT SSPA include an CODAN output power monitoring capability via the monitor and control serial interface.
Power consumption
CODAN Ku-Band VSAT transceivers all feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress.
Power supply
The CODAN 5900 VSAT transceivers features a 48 V DC floating input (37 V to 72 V range) with reverse polarity protection. This is ideal for battery backup and solar-powered systems. In addition, the CODAN 5900 VSAT transceivers may be supplied with an optional CODAN AC power supply unit with field selectable 115/230 V operation.
The AC power supply unit is extremely robust and particularly suited for operation from poor quality AC supplies.
Internal protection
Internal protection against high temperature and short or open circuit RF output is standard. As well, input voltage detection ensures reliable shutdown and restart under brownout or blackout conditions.
External protection
All user access is via a transparent cover, which can be removed without exposing major internal electronics to the elements. Special sealant is used to ensure the sealing integrity of all connectors.
RF modules are fully sealed and pressure tested to 34 kPa (5 psi). Particle and moisture penetration is rated to IP68 and the units are submersible to 3metres.
Advanced features
Enhanced monitor and control
All operating functions can be controlled and monitored via the serial interface. The operating configuration is stored in EEPROM to ensure the setup parameters are restored in the event of a power failure.
Universal interface compatibility
The CODAN 5900 VSAT transceiver has universal interface compatibility capable of operating with dumb terminals, laptop/PC emulating terminals, hand-held terminals and personal organizers without requiring proprietary software. The versatile configuration options support: contact closure, RS232, RS422 and RS485 (2 or 4 wire).
Two dedicated controllers are available from Codan:
CODAN 5560 Hand-Held Controller, suitable for in the field installation setup
CODAN 5570 Remote Controller, suitable for indoor rack mounting to provide permanent monitoring and control capabilities
Redundancy switching system
A redundancy switching system is available to provide an automatic changeover to a second transceiver to maximise link availability and minimise any disruption to service. This system is fully outdoor mounted, but can be supplied with the 5587 Redundant System Monitor to provide indoor monitor and control.

All systems use the common CODAN 5900 series VSAT converter module, which has an RF input of 950-1700MHz. Receive bands are selected by the use of an appropriate LNB. Standard frequency bands are listed above whilst other bands are available on request.
A selection of LNB (phase locked to the internal 10 MHz reference in the 5900 converter module) is available to best meet noise temperature and configuration needs.
