Supporting uplink transmission of satellite signals are Comtech EF Data’s Block Up Converter products. These products cross over into other Comtech EF Data product lines, such as Amplifiers, Terminals and Transceivers.

Our extensive experience in the design of outdoor RF transceivers led to the LPOD family of BUC products’ efficient thermal and mechanical package. Recognizing the evolution of L-Band IF systems, the LPOD is designed to eliminate the traditional requirement for the modem to supply a DC power source and a 10 MHz reference to the BUCs and LNBs. The LPOD’s optional internal reference and LNB bias T greatly simplify multi-carrier operation and provide cost-effective redundant solutions. Featuring an internal power supply, internal reference, and internal LNB bias capability, the LPOD units offer very cost effective solutions for 1:1 redundant Tx and 1:1 redundant Rx requirements. And, the compact size and weight make the units ideally suited to installations with limited mounting space.

Offering the same superior performance as our indoor amplifiers, the HPOD series of C-, X-, and Ku-Band Solid-State Power Amplifiers provide a cost effective, more reliable replacement for TWT amplifiers in satellite communications terminals.  We offer field replaceable power supplies for our HPOD units, effectively minimizing a limiting MTBF factor in electronic equipment. The design provides conservative thermal performance using forced air-cooling for extreme environments. These are available with an internal reference and require no DC power from the modem.  This greatly simplifies multi-carrier and redundant operation.

A unique, outdoor multi-band RF transceiver, the MBT-4000 performs C-, X- or Ku-Band to L-Band down conversion and L-Band to C-, X-, or Ku-Band up conversion. Band-specific Block Up or Block Down Converters are fastened to the base unit with quick-release fasteners. To change operating bands, simply release the quarter turn hasps and replace the blocks with new units. The rugged construction of the MBT-4000 is ideal for mobile and transportable applications. For a lower cost solution, the MBT-4000B performs L-Band to C- or Ku-Band up conversion and supports an LNB for C- or Ku-Band to L‑Band down conversion.

Both of these products eliminate the requirement for DC or 10 MHz from the modem.  This facilitates multi-carrier and redundant systems.

As an  integrated, single thread SCPC VSAT system, the DST-C meets the needs of single and/or multiple site installations. The DST-C system has three major components:

• BUC – weatherproof unit including an integral L-Band up converter and amplifier
• Low Noise Block Converter (LNB) – low noise receive element with an L-Band interface
• Indoor Unit – complete, variable data rate modem with a high stability reference

The DST-Ku parallels the functionality of the DST-C, except it supports Ku-Band.

The LCSA-4 combines and splits signals for L-Band modems and operates as a redundancy controller for RF switches located at the antenna.
