The RF marketplace has been transitioning from traditional 70/140 MHz IF-based networks to systems using L-Band (950 to 2000 MHz) for the modem/RF equipment link, and ComTech EF Data is taking this opportunity to debut their MBT-5000 L-Band Up/Down Converter System.

The MBT-5000 Up/Down Converter System provides this frequency conversion between L-Band IF and C-/X-/Ku-Band RF frequencies. Featuring a drop down front panel providing access to two “hot swappable” frequency conversion modules, this unit offers either a mix of conversion functionality or 1:1 redundant system operation. Designed for rack mounting , the MBT-5000’s 1RU 19-inch chassis front panel contains all operator controls, indicators and displays for local and remote with RF, IF, power, and communications interfaces on the rear. When configured with the redundancy option, the main chassis contains two diode “OR-ed” internal power supplies for increased reliability along with the necessary IF/RF switches. Providing the level of RF frequency conversion performance that has historically been associated with 70/140 MHz rack mount converter systems, the MBT-5000 provides a smooth IF infrastructure upgrade path. The unit's key features include...

• Meets or exceeds IESS 308/309
• Facilitates 188-164A system compliance
• Low phase noise
• Powerful M&C support
• Ethernet/Telnet/SNMP
• EIA 232/485
• Flexible configuration
• RF Band switching in minimal time without requiring tools
• Available 1:1 redundancy in a 1RU chassis

The flexibility of the MBT-5000 makes it ideally suited for Earth stations where L-Band IF products are being integrated into a 70/140 MHz IF infrastructure and for reconfigurable Multi-Band requirements that are typically found in transportable / flyaway type installations.
