VSAT C-Band high power CODAN 5700 transceivers

CODAN 5700 series C-Band high power 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, extended VSAT C-Band  frequency bands and 70 or 140MHz IF configurations-and a range of power outputs-the CODAN 5700  series high power VSAT transceivers  provide industry leading technical performance.

Key features

Durability

The CODAN 5700 series high power VSAT transceivers  are designed and tested to meet their performance specifications in an ambient temperature range from -40°C to +55°C, ensuring long-term survival in extreme conditions. Field experience shows that MTBF of greater than 60,000 hours can be expected.

RF performance

RF performance is superb, particularly intermodulation  performance, gain stability over temperature and flatness across the IF band. These transceivers also boast 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 high linearity and low spurious characteristics contribute to superior multi-carrier performance.

Output power options

The CODAN 5700 series C-Band high power VSAT transceiver is available with 60 watts and 120 watts output power rating.

Power consumption

CODAN high power VSAT transceivers feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress.

Power supply

All the high power transceivers are AC mains powered and may be field selected to operate from either 115 V AC or 230 V AC.

Internal protection

Internal protection against high temperature and short or open circuit RF output is standard.

Advanced features

Enhanced monitor and control

All operating functions can be controlled and monitored via the serial interface, and the operating configuration is stored in EEPROM to ensure the set-up parameters are restored in the event of a power failure.

Universal interface compatibility

The CODAN 5700 series high power VSAT transceivers  has universal interface compatibility capable of operating with dumb VSAT terminals, laptop/PC emulating terminals, handheld 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 VSAT transceiver to maximize availability and minimize any disruption to service. This system is fully outdoor mounted, but can be supplied with the CODAN 5587 Redundant System Monitor to provide indoor monitoring and control.
