COMTECH EF DATA PS 1 High Power Outdoor Amplifier Instructions

COMTECH EF DATA PS 1 High Power Outdoor Amplifier

Product Information

The LPOD C-, X- or Ku-Band Block Up Converter (BUC)/SSPA Amplifiers are high- performance RF amplifiers designed for satellite communication systems. They are available in three models: PS 1, PS 1.5, and PS 2. These amplifiers offer various features and capabilities to enhance the performance and reliability of satellite communication systems.

Optional Internal 10 MHZ Reference:
The LPOD BUC/SSPA amplifiers can be equipped with an optional high-stability, oversized reference oscillator (OCXO). This reference oscillator eliminates any reference degradation caused by IF combiners, interconnections, or rotary joints, ensuring optimum RF performance of the BUC.

Optional Single and Multi-Band LNB Support:
The LPOD amplifiers support both single and multi-band LNBs, providing flexibility in satellite communication systems. With internal power supply, internal reference, and internal LNB bias capability, the LPOD amplifiers offer a cost-effective solution for redundant TX and RX requirements.

Integrated Power Supply:
All LPOD models have a self-contained power supply, eliminating the need for the modem to supply the BUC voltage on the center conductor of the RF cable. This simplifies multi-carrier operation and modem spares maintenance.

Data Logging Capability:
The LPOD amplifiers include built-in data logging capability. Critical operational parameters such as temperature, output power, mute status, etc., are recorded at time-stamped intervals. This data logging feature enhances system maintainability by providing intelligence about the unit and its operational environment.

Advanced FSK:
The LPOD amplifiers, when used with compatible modems, offer additional functionality through the industry-standard FSK communications channel. This feature allows full control of single thread and redundant systems from the modem front panel without additional cabling or cost. The LPOD can also be accessed and controlled via the Ethernet port of the modem using Embedded Distant-end Monitor and Control (EDMAC).

Hand-Held Controller Devices:
The LPOD amplifiers are compatible with various hand-held controller devices, including the LPODnet M&C Accessory Kit and the CLC-10 M&C Accessory Kit. These devices provide easy access to the monitor and control functionality of the LPOD amplifiers.

Product Usage Instructions

1. Connect the LPOD BUC/SSPA amplifier to the satellite communication system according to the system’s installation guidelines.
2. If desired, install the optional high-stability, oversized reference oscillator (OCXO) to improve RF performance by eliminating reference degradation.
3. If using single or multi-band LNBs, ensure that the LPOD amplifier is capable of supporting them.
4. Power on the LPOD amplifier using its integrated power supply. This eliminates the need for the modem to supply BUC voltage on the RF cable.
5. If data logging capability is required, configure the LPOD amplifier to record critical operational parameters at desired time intervals.
6. If using the advanced FSK functionality, ensure compatibility between the LPOD amplifier and the modem. Connect them using the FSK communications channel or Ethernet port.
7. If desired, utilize hand-held controller devices such as the LPODnet M&C Accessory Kit or the CLC-10 M&C Accessory Kit for easy access to monitor and control functionality.

Models

Overview

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 L-Band BUC products.

Optional Internal 10 MHZ Reference

With the optional high-stability, oversized 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, or rotary 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 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. 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 the center 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 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.

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 or cost. The LPOD can also be accessed from the Ethernet port of the modem and controlled via Embedded Distant-end Monitor and Control (EDMAC).

Hand-Held Controller Devices

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