MBT-4000 Frequency Converter Multi-Band RF Transceiver

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. The Comtech MBT-4000 and MBT-4000B Multi-Band RF Transceivers are designed to perform C, X, Ku or Ka RF to L-Band down conversion and L-Band to C, X, Ku or Ka RF up conversion. The MBT-4000 supports two independent converter modules. The MBT-4000B supports one up converter module and also provides the bias, reference, and monitoring of one LNB.

The transceivers also provide the following features:

• RF band switching in minimal time without requiring tools
• Minimal cost for a complete system including spares
• Easy expansion for providing a redundant system or other frequency bands
• Rugged construction for mobile and transportable applications
• Automatic band identification for the BUC, BDC, and antenna feed (if the feeds provide an identifying connector)
• Meets or exceeds MIL-STD-188-164A
• Low phase noise
• No spectral inversion
• 10 dB gain adjustment
• Auto band sensing capability
• Easy system status verification via LEDs located behind a removable cover
• 1:1 redundant up and down conversion which can be “Chain switched” with external amplifiers and LNA/LNBs

Applications

The flexibility of the MBT-4000 & MBT-4000B make them ideally suited for:
• Earth stations where L-Band IF products are being integrated into a 70/140 MHz IF infrastructure
• Reconfigurable multi-band requirements that are typically found in transportable / flyaway type installations
