    Chapter 1. INTRODUCTION 1.1 I NTRODUCTION The High-Power Outdoor (HPOD) Solid-State Power Amplifier (SSPA) shown in Figure 1-1 delivers its rated power, guaranteed, at the 1 dB compression point, to the transmit waveguide flange. It provides a cost effective, more reliable replacement for TWT amplifiers in satellite communications.

  • Page 14: Field Replaceable Power Supply

    EDUNDANCY ONTROLLER Each Comtech EF Data HPOD has the ability to function as a 1+1 (one backup for one primary) and 1+2 (one backup for two primary) redundant controller in the backup mode. The optional redundancy configuration is implemented by attaching a ganged waveguide/coax transfer switch(es) to the input and output connectors of the amplifiers with a combination coaxial cable and waveguide kit.

  • Page 15: Option Free

    Introduction 1.6 O PTION Comtech EF Data’s HPOD series of SSPAs come equipped with useful features that other manufacturers offer as options. Included in the base price are temperature compensation, sample ports, power monitor, field replaceable power factor corrected supply, and full remote monitor and control capabilities.

  • Page 20 The Redundant Loop Connector J4 is located near the waveguide output and is only utilized in configurations where the SSPA controls waveguide switching. In alternate configurations, such as “chain switching”, another system block or external M&C controls the waveguide switching. In this case, the connector remains unused and the protective cap should be left attached.

    The M&C is also capable of acting as a controller in certain 1:1 or 1:2 redundant systems. When configured as the back-up SSPA in such a system, it communicates with the other SSPA(s) and toggles the waveguide switches as necessary.

    Chapter 4. CUSTOMER COMMANDS 4.1 I NTRODUCTION This section describes the operating features of the SSPA. A few key parameters and procedures are summarized, followed by detailed instructions of remote control communication commands. 4.2 RF I NPUT EVEL The required RF input level to reach the full rated output power of the SSPA is determined by the individual amplifier maximum gain and power rating.

  • Page 28: Faults

    • Either fan less than 25% of maximum speed • I2C internal bus communications fault • Thermal Shutdown - A temperature fault is indicated if the unit is ≥ +95°C. This creates a summary fault and will cause the unit to mute itself and switch to the back-up unit (if in a redundant system).
