VSAT C-Band Transceiver CODAN 5700 series

CODAN 5700 series VSAT transceivers offer a wide range of distinctive advantages and enhanced features for satellite communications systems based in remote or challenging geographic regions.

Available in single or dual synthesizer options, standard or extended C-Band operation and 70 or 140 MHz IF configurations-and a range of power outputs-the CODAN 5700 provides industry leading technical performance.

Key features

Durability

The CODAN 5700 VSAT series 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: inter modulation performance, gain stability over temperature and flatness across the IF band. The CODAN 5700 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 5700 transceiver  high linearity and low spurious characteristics contribute to superior multi-carrier performance.

Output power options

Output ratings of 5, 10, 20, 30 and 40 watts are standard, while higher power options are also available.

Power consumption

CODAN VSAT C-Band transceivers all feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress. For example, the 5W system uses a maximum of 95 W, SSPA on, while the 30 W uses 220W maximum.

Power supply

The CODAN VSAT 5700 transceiver 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  5700 VSAT transceivers  may be supplied with an optional 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 5700 VSAT transceiver  has universal interface compatibility capable of operating with dumb terminals, laptop/PC emulating terminals, hand-held terminals and personal organisers 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.
