VSAT BUC CODAN 6700 and 6900 High Power Block Up Converters

 VSAT BUC Codan 6700/6900 series User Guide (1 MB)

CODAN VSAT High power Block Up Converter (BUC) systems offer a wide range of distinctive advantages and enhanced features for satellite communications systems based in remote or challenging geographic regions.

Available in the standard VSAT C Band and VSAT Ku-Band operating frequencies-and a range of output powers-the BUCs provide industry leading technical performance.

Configuration

The VSAT High power BUC systems are based on Low power Block Up Converter (LBUC) driving a high power solid state VSAT power amplifier (SSPA). The SSPA is available with 120 watts (VSAT C Band) or 40 watts (VSAT Ku Band) of RF output power.

Durability

The High power VSAT BUC systems are designed and tested to meet their performance specifications over an ambient temperature range of -40°C to +55°C and up to 100% relative humidity, ensuring long term survival in extreme conditions. Field experience for CODAN VSAT BUCs shows that MTBFs of greater than 100,000 hours can be expected.

RF performance

RF performance is superior, particularly: intermodulation performance, gain stability over temperature and flatness across the IF band. The CODAN VSAT BUC systems also boast industry leading spurious and harmonics specifications. Guaranteed RF performance ensures expensive system link margins do not have to be used to cope with RF transceiver variations.

Power

CODAN High power VSAT BUC systems all feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress. The CODAN VSAT LBUC modules are powered via the transmit IF cable, and the CODAN VSAT SSPAs are AC mains powered.

Internal protection

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

External protection

The CODAN VSAT BUCs and CODAN VSAT SSPAs are completely protected from the elements without external user controls. All modules are fully sealed and pressure tested to 34 kPa (5 psi).

Advanced features

Enhanced monitor and control

All operating functions can be controlled and monitored via the serial Monitor & Control (M&C) facilities.

The operating configuration is stored in EEPROM to ensure the set-up parameters are restored in the event of a power failure.

The CODAN VSAT LBUCs have universal interface compatibility and are capable of operating with dumb terminals and laptops/PCs emulating terminals.

CODAN provides the optional Hand-held VSAT Controller CODAN 6560 for easy set up of the CODAN VSAT LBUCs.

The user has the choice of an FSK based M&C interface, which is fed via the transmit IF cable for use with intelligent modems or separate RS232 or RS422/RS485 interfaces.

Multiple M&C protocols are provided to enable integration into a number of network management systems.

The user-friendly, PC-based SSPA Manager is provided for operator control and monitoring of the SSPA.
