1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom 7-Rack Unit
Solid State Power Amplifier (SSPA) Chassis. This includes a description of the unit and safety
precautions.
1.1 Description
The Teledyne Paradise Datacom 7RU Rack-Mountable SSPA Chassis employs a modular
design, which allows quick and easy replacement in the event of a catastrophic failure of one
of the SSPA components. These modular assemblies include: hot-swappable SSPA modules;
front and rear fan trays; and a rear panel controller card.
The indoor rack mounted unit contains an internal microprocessor which allows for full
monitoring and control from the front panel’s 2x40 Vacuum Florescent Display and push-
buttons, or via a remote serial (RS-232 or RS-485) or parallel connector.
The microprocessor monitors various voltages, currents and temperatures within the unit for a
full fault analysis. The user also has the ability to select additional faults related to the RF
output level, an optional reflected power level and operating temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF signal.
Temperature compensation limits the amplifier’s output response from varying significantly
over the operating temperature. Also, the system contains input and output sample ports.
The power supply for the 7RU SSPA Chassis is a separate 3RU Power Supply Chassis,
which houses three power supply modules. Only two of these modules are required to power
the SSPA, therefore the third module is redundant. In the event of a power supply module fail-
ure, the amplifier system will not fail.
1.2 Specifications
Refer to the specification sheet in Appendix C for complete specifications.
1.3 Equipment Supplied
The following equipment is supplied with each unit:
• High Power SSPA Chassis RM (7 RU high)
• Power Supply Chassis (3 RU high) (standard)
• Rack Slides
• Interconnecting Cables to Bus Bar
• Operations Manual, High Power SSPA Chassis [208528]

1.4 Inspection
When the unit is received, an initial inspection should be completed. First ensure that the
shipping container is not damaged. If it is, have a representative from the shipping company
present when the container is opened. Perform a visual inspection of the equipment to make
sure that all items on the packing list are enclosed. If any damage has occurred or if items are
missing, contact:
Teledyne Paradise Datacom LLC
328 Innovation Blvd., Suite 100
State College, PA 16803 USA

1.5 Rack Mounting
The SSPA Chassis is designed to fit in a standard 19” wide EIA rack. The unit is 7 rack units
or 10.47 inches (266 mm) high by 33.75 inches (857.3 mm) deep (including connectors and
bus bar), and weighs 180 pounds (82 kg). The power supply chassis is 3 rack units or 5.25
inches (133.4 mm) high by 20.42 inches (518.7 mm) deep, and weighs 50 pounds (23 kg)
with all three power supply modules installed.
1.6 Shipment
To protect the SSPA Chassis during shipment, use high quality commercial packing methods.
When possible, use the original shipping container and its materials. Reliable commercial

1.7 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.
1.7.1 High Voltage Hazards
High Voltage for the purpose of this section is any voltage in excess of 30
volts. Voltages above this value can be hazardous and even lethal under
certain circumstances. Care should be taken when working with devices that
operate at high voltage.
• All probes and tools that contact the equipment should be properly insulated to prevent
the operator from coming in contact with the voltage.
• The work area should be secure and free from non-essential items.
• Operators should never work alone on high voltage devices. There should always be an-
other person present in the same work area to assist in the event of an emergency.
