PS 2Overview
Our extensive experience in the design of outdoor RF transceivers led to the LPOD family’s 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. The LPOD offers valuable features not found in other LBand BUC products.

Optional Internal 10 MHZ ReferenceWith the optional high-stability, ovenized reference oscillator (OCXO) installed, one more signal is removed from the TX IF cable. This
ensures optimum RF performance of the BUC by eliminating any reference degradation caused by IF combiners, interconnections orrotary joints.

Optional Single and Multi-Band LNB Support
The LPOD was designed with the evolution of L-Band systems in mind. No longer relegated to low power single carrier installations,
L-Band IF topologies are now found in larger multi-carrier installations. A challenge presented by multi-carrier L-Band systems is thepresence 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. We also offer a high-stability“Multi-Band” Ku LNB facilitating global Ku-Band downlink coverage controlled by the LPOD M&C.

Redundancy
Another challenge addressed by the LPOD topology is the increasing need for redundant L-Band RF solutions. With its internal power
supply, internal reference and internal LNB bias capability, the LPOD offers a very cost-effective solution for 1:1 redundant TX and
1:1 redundant RX requirements.

Integrated Power Supply
All LPOD models have a self-contained power supply. This eliminates the requirement for the modem to supply the BUC voltage on thecenter conductor of the RF cable, simplifying multi-carrier operation and modem spares maintenance.

Data Logging Capability
To greatly enhance system maintainability, the LPOD line includes a built-in data logging capability. By recording critical operationalparameters (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.

Advanced FSK
When used with our modems, the LPOD provides valuable additional functionality utilizing the industry standard FSK communications
channel. This feature offers full control of single thread and redundant systems from the modem front panel without additional cabling orcost. The LPOD can also be accessed from the Ethernet port of the modem and controlled via Embedded Distant-end Monitor andControl (EDMAC).

Hand-Held Controller Devices
A variety of hand-held controller devices are available. These include the LPODnet M&C Accessory Kit andthe CLC-10 M&C Accessory Kit. Both are designed to access the monitor and control functionality of theLPOD family of products.
