Low Power Outdoor (LPOD) Amplifier/Block Up Converter (BUC)
Revision 15
Introduction 1–3 MN-LPOD
1.3.4 “Smart BUC” Functionality
CEFD’s unique approach to L-Band/RF frequency conversions eliminates DC and 10 MHz from
the input coax. This simplifies redundant and multi-carrier operation. Full 13.75 to 14.5 GHz Ku
coverage and 5850 to 6725 MHz C-band coverage is offered while supporting industry standard
Frequency Shift Keying (FSK) modem/BUC communications, as well as CEFDs proprietary
commands.
Both LPOD models have a self-contained power supply, eliminating the requirement for the
modem to supply the BUC voltage on the center conductor of the RF cable, simplifying multi-
carrier operation and modem spares maintenance.
1.3.5 Data Logging Capability
To greatly enhance system maintainability, the LPOD includes a built-in data logging capability.
By recording critical operational parameters (such as temperature, output power, mute status,
etc.) at time stamped intervals, the user can quickly gather intelligence not only about the unit
itself, but also the unit’s operational environment.
1.3.6 Optional Internal 10 MHz Reference
With the optional high stability, oven-controlled crystal oscillator (OCXO) installed, one more
signal is removed from the TX Intermediate Frequency (IF) cable. This ensures optimum RF
performance of the BUC by eliminating any reference degradation caused by IF combiners,
interconnections, or rotary joints.
1.3.7 Optional LNB Support
The LPOD was designed with the evolution of L-band systems in mind. L-band IF topologies are
no longer relegated to low power single carrier installations, and are now found in larger multi-
carrier installations. A challenge presented by multi-carrier L-band systems is the presence of DC
and reference components on the Tx/Rx L-band interfaces. The LPOD design, by default,
eliminates the DC component from the Tx IF and can eliminate the reference requirement with
the optional internal OCXO. The LNB bias/reference option completes the solution by eliminating
DC and reference signal requirements from the Rx L-band interface.
