“standard” 14.0 GHz‐to‐14.5 GHz HPOD has an L‐Band frequency range of 1200 MHz‐to‐1700 MHz that translates up to 14.0 GHz‐to‐14.5 GHz, while the “Extended” 13.75 GHz‐to‐14.5 GHz HPOD translates L‐Band frequencies from 950 MHz‐to‐1700 MHz up to 13.75 GHz‐to‐14.5 GHz. Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L‐Band coax. In addition, the BUC version of the HPOD 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. 1–6...

Never turn the unit ON without proper waveguide termination on the J2 RF OUTPUT port. Individuals can be exposed to dangerously high electromagnetic levels. The HPOD SSPA does not contain a ‘Power On/Off’ switch. The SSPA is powered ON by connecting the J3 | AC IN Power connector to the appropriate prime power source. The Mute or Transmit status of the SSPA will automatically come up in the last stored state (factory default = Transmit on, not muted). ...

Chapter 5. SERIAL-BASED REMOTE PRODUCT MANAGEMENT Overview This chapter describes the protocol and message command and query set for complete remote monitor and control of the HPOD SSPA. It also summarizes key operational parameters and some of their most commonly‐used remote commands and queries. Key Operational Parameters See Sect.5.5 Remote Commands and Queries for detailed information about the remote commands and queries mentioned in this section. 5.2.1 RF Input Level The individual amplifier maximum gain and power rating determines the RF input level required to reach the full rated output power of the HPOD. For example: If the test data of an SSPA rated for 250W (54 dBm) indicated a gain of 75 dB, then a signal of 54dBm – 75 dB = ‐21 dBm would approximately give the rated output power. Increasing input power beyond this level results in an output signal with increasingly higher levels of distortion. Of course, if the SSPA attenuation control is utilized, a higher‐level input signal level can be accommodated. 5–1...
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier Revision 6 Serial-Based Remote Product Management MN/HPOD.IOM Permanent damage may occur to the unit if the maximum input level exceeds 15 dBm. 5.2.2 Attenuator Control Execute the “ATT” command to attenuate HPOD gain over a 30 dB range. 5.2.3 Mute Control The amplifier may be muted via software or discrete control: • Execute the MUT=1 command to “software” mute the unit.

They may not appear anywhere else within the body of the message. 5.3.4.2 Target Address Up to 9,999 devices can be uniquely addressed; in both EIA‐485 and EIA‐232 applications, the permissible range of values is 1 to 9999. The address is programmed into a Target unit using the remote control port. The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds, the address used is the same address, to indicate to the Controller the source of the packet.

Appendix A. REDUNDANCY SYSTEM ASSEMBLY KITS Introduction Several kits are available from Comtech EF Data to mount and install HPOD 1:1 or 1:2 Redundancy Systems, tailored to the operational frequency of the system. The figures and tables provided in the subsections that follow provide examples of these currently available kits. Once all system kit components have been assembled, and all interconnecting RF and M&C cables have been installed, see Appendix B. 1:1 AND 1:2 REDUNDANCY OPERATION for further information about configuring, operating, and troubleshooting your HPOD 1:1 or 1:2 Redundancy System.

Appendix B. 1:1 AND 1:2 REDUNDANCY OPERATION Introduction Comtech EF Data’s C‐, X‐, and KU‐Band High‐Power Outdoor Power Amplifiers (HPODs) can be used in redundant configuration by connecting the appropriate redundancy loop cable between the user M&C location and each HPOD ‘J4 | REDUNDANT LOOP’ port. This 1:1 or 1:2 cable has connector pinouts that allow the HPODs to both automatically detect the type of cable in use and, when properly connected between the user and the redundancy setup, automatically configure itself for operations in accordance with the labeling for each cable connector (SSPA 1 or SSPA 2 for a 1:1 system, or SSPA 1, SSPA 2, or SSPA BU for a 1:2 system). B.1.1 1:1 Redundancy Mode In 1:1 redundancy mode, the unit that is currently not the active unit (determined by the switch position) will be the controlling Backup Unit (BU). The redundancy system’s operating mode is determined by using the “RAM” serial remote ...

Figure B-1. HPOD C-Band 1:2 Redundancy System Block Diagram In 1:2 redundancy mode there is a dedicated BackupUnit (designated as BU) as determined by the cable position. In this configuration, the BU is responsible for monitoring the two online units for communications and summary faults. While the BU is constantly monitoring both units for their status, if either has a fault, use the last (good) status as the configuration for the BU before the BU goes online. Once the BU goes ...
