VSAT BUC Codan 6700/6900 User Guide (1 MB)
VSAT L-Band IF input CODAN 6700 series VSAT C-Band and CODAN 6900 series Ku-Band 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 all common VSAT C-Band and VSAT Ku-Band operating frequencies-and a range of output powers - the CODAN 6700 and CODAN 6900 series provide industry leading technical performance.
Key features
Configuration
The CODAN 6700 and CODAN 6900 series VSAT BUC are based on a compact L-Band IF input Block Up Converter (BUC). This module is available in VSAT C-Band and VSAT Ku-Band versions and a range of RF output powers. Receive capability is provided by a range of LNBs to cover the various VSAT C-Band and VSAT Ku-Band receive frequency ranges.
Durability The CODAN 6700 and CODAN 6900 series VSAT transceivers are designed and tested to meet all 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 transceivers 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 6700 and 6900 series VSAT transceivers also boast industry leading spurious and harmonics specifications compliant with CE requirements. Guaranteed RF performance ensures expensive system link margins do not have to be used to cope with RF transceiver variations.
Power
CODAN L-Band IF VSAT transceivers all feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress.
The CODAN 6700 and CODAN 6900 series Low power VSAT (LBUC) modules are powered via the transmit IF cable. The Medium power VSAT (MBUC) modules are AC mains powered.
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
The VSAT transceiver is completely protected from the elements without external user controls. The VSAT BUC modules are fully sealed and pressure tested to 34 kPa (5 psi). Particle and moisture penetration is rated to IP68. High quality powder coat paint is used to protect the modules from corrosion.
Advanced features
Enhanced monitor and control
All operating functions can be controlled and monitored via the serial M&C facilities. The standard output power meter facility features high accuracy and the ability to measure both CW and burst mode signals.
The CODAN 6700 and CODAN 6900 series VSAT transceivers is capable of operating with a PC without requiring proprietary software.
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.
IF Interface unit
In cases where the modem is not able to drive the transceiver directly, an optional indoor unit is available. This unit connects to the modem at the L-Band transmit and receive IF interfaces, and multiplexes the required power and reference signals on the IF cables. In addition, it also converts the M&C FSK to separate RS232 and RS422/RS485 interfaces.
Major configuration options
Refer to individual specification sheets for allowed combinations of configuration options.
Receive frequency bands (GHz)
Receive bands are selected by the use of an appropriate LNB. Standard frequency bands are listed below. Noise temperatures of 40 K (C-Band) and 75 K (Ku-Band) are available.
