User Guide Ku Band Solid State Amplifiers – SSPA Redundant Configuration
Outdoor Band Solid State Amplifier System – Redundant Configuration User Guide This section provides general information for the UPCOM TECHNOLOGIES line of Outdoor Solid State Amplifers – SSPAs with Built-In Redundancy Configuration Option. The Outdoor SSPA has been designed and manufactured to be extremely robust and reliable. It is well suited for harsh outdoor environments. Description Please refer to Appendix A for the appropriate product data sheet and specifications.
General Information Safety Considerations Potential safety hazards exist unless proper precautions are observed when working with this unit. To ensure safe operation, the user must follow the information, cautions, and warnings provided in this manual as well as the warning labels placed on the unit itself. High Voltage Hazards Only qualified service personnel should service the internal electronic circuitry of the Outdoor SSPA.
Ports and Interfaces Prime Power Connection The Prime Power Connector is the point where the unit receives input power. A connector 3100A 14S-7P is used. The AC input can operate over a range of 90 - 270 VAC, at 47 - 63 Hz.
The maximum input level should be limited to +33 dBm to avoid damaging the unit. RF Output The RF Output is brought out through waveguide in the Outdoor SSPAs. The Ku Band SSPAs have a WR-75 Grooved Flange while the C Band SSPAs have CPR style grooved flange (CPR-137G). An isolator is provided at the output flange with a termination capable of handling full reflected output power.
D Tx- Airflow The air intake and exhaust are both located on the bottom side of the SSPA. The intake is brought through one or two fans ( two fans on 50 watts units KU Band and higher and one fan on lower power units) while the exhaust is along the rows of heat-sink fins. A minimum clearance of 12 inches (305 mm) should be maintained between the air intake of the Outdoor SSPA and exhaust during operation. This will ensure that there is no forced recirculation of airflow from exhaust to intake.
Monitors and Controls Monitor signals and Control lines are present on the M & C Connector when this option is installed. Typically, single threaded units are NOT equipped with micro-controller by default. With a Microcontroller equipped system, all Monitors and Controls can also be accessed remotely by RS-232 / RS-485.to a Windows based PC; and other Alarms become available as well. Units equipped with a Redundancy option have a Microcontroller M & C installed by default.
UPCOM TECHNOLOGIES Temperature Monitor The temperature of the unit baseplate is monitored by a voltage analogous to temperature. The output is 3.0 V at 27 ºC with a slope of 10 mV / ºC. RF Output Power Monitor The output power of the unit is monitored by a voltage analogous to the output power level. The voltage is restricted to in between 0 V to 5 V. This detected voltage is useful over a 20 dB range of output power.
UPCOM TECHNOLOGIES Status Display (Optional ) This indicator shows the general status of the Outdoor SSPA – if everything is good, or if an error condition has occurred, or if the unit has been manually disabled by mute control. Also, the operating status of a Master/Slave redundant pair is reflected.
UPCOM TECHNOLOGIES Temperature Compensation Tighter temperature compensation response is also possible with the attenuator module installed. There is no user control here, and the unit must have the requisite hardware option installed, and be calibrated at the factory for this function to be active. Communication Status (Optional ) The communication status between the software and the SSPA is reflected here.

UPCOM TECHNOLOGIES Quick Start Guide Check the connectivity of the AC Pins and also at the AC Cable to make sure that Line or Neutral pins are NOT connected to the ground Connect the low power KU Band output from a low power BUC or indoor upconverter to the labeled port. Nominal input levels are approximately +20 dBm depending on the output power level of the unit.
UPCOM TECHNOLOGIES General Maintenance With proper care and maintenance, your SSPA will provide many years of reliable service. Please follow these maintenance guidelines so that your equipment will provide you with the maximum amount of trouble-free service. Basic Cleanliness The exterior chassis of the SSPA acts as a large heatsink that must dissipate at least a few hundred Watts.
UPCOM TECHNOLOGIES Theory of Operation AC / DC Converter The prime AC input power is delivered to a converter module that produces 300 VDC. This module is an auto-sensing front end that has proven reliability and allows the amplifier system to operate over a wide variety of input power conditions encountered around the world. DC / DC Converter The DC/DC converter module is a switched mode power supply that converts the 300 VDC to 12 VDC.
