    The warranty does not apply to any part of a product that has been installed, altered, repaired, or misused in any way that, in the opinion of Comtech EF Data Corporation, would affect the reliability or detracts from the performance of any part of the product, or is damaged as the result of use in a way or with equipment that had not been previously approved by Comtech EF Data Corporation.

  • Page 15: Chapter 1. Introduction

    Comtech EF Data’s (CEFD) LGaN family of Outdoor Amplifiers / Block Up Converters (BUCs) – referred to collectively throughout this manual as the LGaN – deliver their rated power, guaranteed, to the transmit waveguide flange. The LGaN provides a cost effective, more reliable replacement for Traveling Wave Tube (TWT) amplifiers in satellite communications.

  • Page 16: Functional Description

    As shown in Figure 1-1 and Figure 1-2, CEFD’s LGaN is available in several sizes and power levels. Each LGaN consists of a CEFD Solid State Power Amplifier (SSPA) module with the Monitor/Control Processor (MCP), a power supply, and a fan assembly.

    IF combiners, interconnections, or rotary joints. 1.3.7 Optional LNB Support The LGaN 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.

  • Page 18: Temperature And Rf Overdrive

    1.3.10.1 Overview The LGaN has firmware intended to help the user be more aware of potential over temperature and over drive conditions that could degrade the reliability of the amplifier. Furthermore, the user can view recorded maximum and minimum values of important parameters as they have occurred over the operating history of the unit.

    Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L-Band coax. In addition, the LGaN is available with an internal 10 MHz reference. As, such, no 10 MHz reference is required on the center conductor of the L-Band coax. If a reference is provided on the coax, the internal reference will detect and lock to it.
