Description
Codan 6908 8W Ku-Band BUC Model 6908-W/E-48/IF-CE 48VDC
48VDC Required, 10MHz Required, LO = 15450MHz
Codan’s L-Band IF input 6900 series Ku-Band Block Up Converters (BUCs) offer a wide range of distinctive advantages and enhanced features for satellite communications systems. Available in a variety of models, the 6900 series BUs provide industry-leading technical performance.
Configuration
The 6900 series compact L-Band IF input Block Up Converters (BUCs) are available in a range of RF output powers.
Durability
The 6900 series 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 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 6900 series also boast industry leading spurious and harmonics specifications. Guaranteed F performance ensures expensive system link margins do not have to be used to cope with RF transceiver variations
CE compatible
While CE certified versions are available, all BUs are designed to ensure that the customer can easily achieve CE certification at a system level for a transmission system in the EU
All Codan BUCs are tested to the following standards:
EMI/EMC Directive
EN 301 489 – 1 (as per Article 3.1b in the RTT&E Directive)
EN 301 489 – 12 (as per Article 3.1b in the RTT&E Directive)
LV Directive
EN60950 (as per Article 3.1a in the RTT&E Directive)
CR1999/519/ECand ICNIRP Guidelines
Power
Codan BUs all feature low power consumption and low temperature rise, ensuring internal components do not suffer undue stress. DC-powered BUs are powered either via the transmit IF cable or optional external DC power connector.
AC-powered BU modules are AC mains powered via an external connector.
Internal protection
Internal protection against high temperature and short or open circuit RF output is standard. Input voltage detection ensures reliable shutdown and restart under brownout or blackout
conditions.
External protection
The BUs are completely protected from the elements, are without external user controls and are fully sealed, and pressure tested to 34 kPa (5 psi). Particle and moisture penetration is rated to IP67. High quality 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&Cfacilities. The standard output power meter facility features high accuracy and the ability to measure both CW and burst mode signals. The 6900 series 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. Multiple M&C protocols are provided to enable integration into a number of network management systems.
