Paradise Datacom’s Indoor, High Power Rack Mount (R) series SSPAs represent the industry’s highest power density and most reliable high power amplifier systems.

The High Power Rack Mount SSPA 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-swap SSPA modules, front and rear fan trays; and a rear panel controller card. These amplifiers are powered via a separate power supply chassis.

The power supply is configured as a n+1 redundant, hot swappable, power supply comprised of three modules. Only two modules are required to operate the HPA, therefore one module is redundant. In the event of a power supply module failure, the amplifier system will not fail. The module can then be changed without ever taking the HPA out of service.

Power Supply Options

The 7RU Chassis may be fitted with a variety of power supply options. The dual 1RU power supply configuration provides redundancy with all power levels; or may be used as a non -redundant supply by utilizing fewer power supply modules. The stand-alone 1RU power supply can be used to power the 750W C-Band or 400W Ku-Band chassis. The standard 3RU, three-module power supply offers redundancy for all power levels.

This allows solid state technology to be used in applications that have long been reserved for TWTAs.

At less than 23 lbs. (10.5 kg), and only slightly larger than a lunch box, this family of SSPAs is available in output power levels in the following range:

C-Band: 75W, 100W
X-Band: 50W, 75W, 100W, 175W
Ku-Band: 50W, 80W

Paradise Datacom offers an Outdoor Fiber Optic Converter Module (OFM-1000) for the Mini Compact Outdoor SSPA which interfaces with a rack mountable Fiber Optic to L Band Transceiver (RCPF-1000).

RF filters, isolators, cooling, and monitor and control (M&C) systems are all self-contained within the package.

Rack space is conserved because the amplifiers occupy only 7 rack units (12.25 inches) of a standard 19 inch rack cabinet. Nominal weight is 140 pounds.

The unit features a menu driven front panel display, RS-232/422/485 serial port and Ethernet interfaces for complete computer control. Forward power, reverse power and temperature, and default parameters are easily monitored on the four line front panel display.

Gain control is provided via the front panel or through the remote interfaces.

A high frequency resonant conversion power supply is used that accepts a wide range of prime power (90 to 264 VAC). Power factor correction circuitry is also included which minimizes line current distortion and reduces the required Volt- Amps input.

The amplifier includes an integrated L-Band Block Upconverter that interfaces to standard modems operating in the 950-1450 MHz range. The L-Band transmit signal and 10 MHz reference are brought to the unit over a single coaxial line.

Depending upon user requirements, this high power amplifier can be configured for single thread, redundant, or phase combined configurations.

The L-Band input interfaces to standard modems operating in the 950 – 1450 MHz range.

Intended for outdoor operation, the XTS-40X-B1 eliminates the need for a separate shelter. The construction and light weight allows for direct mount to the antenna. This eliminates long waveguide runs and associated RF losses.

Forced air cooling is implemented in the package to allow reliable operation over extended temperature ranges. The monitor and control (M&C) interface provides a component system status.

The block upconverter operates from an external, weatherized power supply which provides the system DC sources.

The L-Band transmit signal and 10 MHz reference frequency are brought to the unit over a single coaxial line.

Based on technology used in VertexRSI’s field-proven ModuMAX amplifiers, QuadMod SSPAs utilize field-replaceable RF modules, power supplies and electronic assemblies to maximize performance and minimize downtime in SATCOM systems.

Since solid-state power amplifiers (SSPAs) consist of multiple transistors in parallel, they naturally contain a degree of built-in redundancy. With proper attention to design architecture, the use of multiple parallel RF modules, and the elimination of all active devices from the common RF path, VertexRSI has designed an SSPA that is reliable and extremely fault-tolerant.

Featuring a hot-swappable modular architecture for ease of maintenance, QuadMod SSPAs offer an economical extension of VertexRSI’s patented ModuMAX technology for systems requiring lower RF power output.

Most satellite earth stations cannot afford down time due to equipment failure, so they employ redundancy – two of everything – at a significant increase in cost and complexity. This made sense when the final amplifier stage was a single tube and thus a single point failure. However, now that solid state is a viable and practical amplifier technology, solutions other than brute-force redundancy make better sense.

The ModuMAX SSPA consists of eight identical, fully interchangeable RF plug-in modules that are conveniently accessible from the front panel. Module status is visually indicated by an LED on each module as well as the control panel display.

Complete failure of a module causes a drop of only 1.2 dB in output power without the momentary loss of signal caused by redundant switchover systems. Defective modules can be hot-swapped while the SSPA continues to operate. Spare RF modules are affordable, since they contain only a fraction of the RF power transistors in the SSPA.
