1.1 Overview
Figure 1-1. Comtech EF Data LBC-4000 L-Band Up/Down Converter
Comtech EF Data’s LBC-4000 L-Band Up/Down Converter System ( Figure 1-1 ) is
designed to interface legacy 70 MHz or 140 MHz equipment to tri-band or quad-
band block converters.
1.2 Functional Description
See Chapter 2. SPECIFICATIONS for component specifications.
You may use standard, off-the-shelf coaxial cabling to connect external
equipment (e.g., a modem), to each internal converter module. Use coaxial
cabling to connect the output for each module to RF equipment either at the
same location or at the antenna location. When configured with the redundancy
option, the system may contain two diode “OR-ed” internal power supplies for
increased reliability.
