Chapter 1. INTRODUCTION 1.1 Overview The Comtech EF Data Ku-Band Solid-State Power Amplifier (KPA) family of products, shown in Figure 1-1, is a line of Indoor Solid-State Power Amplifiers (ISSPAs) designed for use in communication systems or satellite uplink data systems. The KPA operates over the RF input frequency range of 14.0 to 14.5 GHz and provides a cost effective and more reliable replacement for Traveling Wave Tube (TWT) amplifiers in Ku-Band terminals.
Ku-Band Solid-State Power Amplifier Introduction 1.2 Revision 1 MN/KPA.IOM Functional Description Each KPA ISSPA is constructed with highly reliable Gallium Arsenide Field Effect Transistors (GaAs FETs). With Third-Order Intermodulation products from 4 to 6 dB better than TWT ratings, the Comtech EF Data unit replaces TWTs with saturated power levels of up to twice the KPA’s rated output. These KPAs also provide a Mean Time Between Failure (MTBF) that is 4 to 5 times greater than the typical TWT MTBFs.

Chapter 2. INSTALLATION 2.1 Unpacking and Inspection The KPA ISSPA and its Installation and Operation Manual are packaged and shipped in a preformed, reusable cardboard carton containing foam spacing for maximum shipping protection. Do not use any cutting tool that will extend more than 1 inch into the container. This can cause damage to the unit. CAUTION Unpack and inspect the unit as follows: Step Procedure 1 Inspect shipping containers for damage.
KPA Ku-Band Indoor Solid State Power Amplifier Installation 2.2 Revision 1 MN/KPA.IOM Rack Mounting the KPA The KPA is designed to be rack-mounted in a standard 19-inch (48 cm) rack or cabinet by hardmounting the unit to the rack’s front mounting rails using the front panel mounting holes/ Handles at the front of the units facilitate easy installation into and removal from the rack.

Appendix B. KPA REDUNDANT OPERATIONS B.1 Introduction IMPORTANT Comtech EF Data’s KPA family of ISSPAs are designed to automatically sense and configure into Redundancy Mode when the redundant loop cable is connected. Polling on the dedicated redundancy bus will not begin until the redundancy loop cable is connected. Each KPA’s designation in a redundant subsystem is determined automatically via the redundancy interface cable connected between the two (i.e., 1:1) or three (i.e.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B B.2 Revision 1 MN/KPA.IOM Redundancy Operation Figure B-1. 1:1 Redundancy Block Diagram Figure B-1 shows the block diagram for a typical 1:1 redundant system. Whether 1:1 or 1:2 redundant operations are employed, note the following: B.3 Normal Operation Incoming RF signals are routed through the primary online SSPA (1:1), or SSPA (1:2) to the system output(s) by the combination waveguide/coax switch(es).
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B Revision 1 MN/KPA.IOM they are not shown in this manual. Contact Comtech EF Data for 1:2 Redundancy Kits and their pertinent installation diagrams and assembly instructions. Perform the installation as follows (refer also to Figure B-2 and Figure B-4): Step Procedure 1 Assemble the waveguide load and bend to the proper port of the switch. 2 Attach the rigid lower waveguide arm, using the supplied screws.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B B.3.1 Revision 1 MN/KPA.IOM Redundancy Kit Control Cabling For either a 1:1 or a 1:2 redundant system, two control cable assemblies are required for setup as shown in Figure B-3. Other RF coaxial cables and waveguides are required as shown in Figure B-4. 1:1 System Control Cabling 1:2 System Control Cabling Figure B-3.

KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B B.4 Revision 1 MN/KPA.IOM Gain Equalization of Redundant Units To equalize the gain between the Backup Unit and the Online Unit(s), Gain Offset adjustment is accomplished via the Backup Unit. Before continuing, make sure that: IMPORTANT a) All external interface connections have been completed as outlined in Sect. B.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B B.4.1 Revision 1 MN/KPA.IOM Case Examples Case 1. Backup Å Online unit(s) 1. Ensure the Online Unit attenuation is set to a value in dB greater than or equal (≥ ) to the difference in levels measured above. 2. With the Backup Unit forced to be the active unit, adjust the OFFSET value in the CONFIG: Redundancy Æ SSPA#1 menu to approximately the difference measured previously. This will be a negative (-) number. 3.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix B Revision 1 MN/KPA.IOM Case 2. Backup Æ Online unit(s) 1. With the Backup Unit forced to be the active unit, adjust the Offset Value in the CONFIG: Redundancy menu to roughly the difference measured previously. This will be a positive (+) number. 2. Toggle between the online and Backup Units as being the active path by forcing and unforcing a backup through the Backup Unit’s CONFIG: Redundancy Æ SSPA#1 menu.
Appendix C. REMOTE CONTROL C.1 Overview This appendix describes the protocol and message command set for remote monitor and control of the KPA ISSPA. The electrical interface is either an EIA-485 multi-drop bus (for the control of many devices) or an EIA-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form using ASCII characters.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix C Revision 1 MN/KPA.IOM All of the Targets receive the packet, but only one (the intended) will reply. The Target enables its output line driver and transmits its return data packet back to the Controller in the other direction, on the physically separate pair. EIA-485 (full duplex) summary: C.3 • Two differential pairs – one pair for Controller-to-Target, one pair for Target-to-Controller.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix C C.5 Revision 1 MN/KPA.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix C C.5.2 Revision 1 MN/KPA.IOM Target Address Up to 9,999 devices can be uniquely addressed. In both EIA-232 and EIA-485 applications, the permissible range of values is 1 to 9999. It is programmed into a target unit using the remote control port. IMPORTANT C.5.3 The controller sends a packet with the address of a target - the destination of the packet.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix C Revision 1 MN/KPA.IOM 2. From Target-to-Controller, the only permitted value is: Symbol = (ASCII code 61) Definition The = code is used in two ways: First, if the controller has sent a query code to a target (for example MUT?, meaning ‘is mute enable or disable?’), the target would respond with MUT=x, where x represents the state in question: 1 being ‘enable’ and 0 being disable.
KPA Ku-Band Indoor Solid-State Power Amplifier Appendix C C.5.7 Revision 1 MN/KPA.IOM End of Packet Controller-to-Target: This is the ‘Carriage Return’ character (ASCII code 13). Target-to-Controller: This is the two-character sequence ‘Carriage Return’, ‘Line Feed’ (ASCII codes 13 and 10). Both indicate the valid termination of a packet. For the error message or the old remote command, it is the three-character sequence ‘Carriage Return’, ‘Line Feed’, ‘]’ (ASCII codes 13, 10, and 93).
