VertexRSI Red. Outdoor SSPA System, 40W, model PKO14S030N
The VertexRSI Red. Outdoor SSPA System, 40W, model PKO14S030N is ready for sale. These high-power solid-state amplifiers offer output powers of 40 or 50W across the standard 14.0 to 14.5 GHz (“M”) satellite uplink band. This 40W Red. SSPA System is available for the extended 13.75 to 14.5 GHz (“O”) band. Housed in a weatherproof enclosure, the amplifiers can be mounted in new or used Earth Station Antenna hubs or outdoors in applications where it is desirable to reduce cable losses by mounting the SSPA close to the antenna. Built for reliable, trouble-free service, the amplifiers incorporate a microprocessor-based monitor and control system.

Functional Description
These rugged, reliable, solid-state power amplifiers deliver the power output of a TWTA yet achieve lower intermodulation distortion and longer lifetime than tube type amplifiers. The weatherproof enclosure, designed for outdoor structure or antenna king-post mounting, provides additional benefits. Extensive waveguide, coax, or fiber optic runs can be minimized, reducing associated losses. With the optional block upconverter (BUC), the SSPA can operate directly from L-Band IF input.
VertexRSI has incorporated a number of features into its in-house all GaAs FET SSPA module, including low loss power combining techniques, active bias regulation for stable Q-point vs. time and temperature, microprocessor-based current fault monitoring of each RF power FET, and low dropout dc regulation to minimize wasted power.
The amplifiers incorporate complete thermal management, optimized by thermal analysis CAD software to deliver lower device junction temperatures. The forced-air cooling system draws cool air in and across an external heatsink without disturbing the weatherproof integrity of the SSPA enclosure.
The SSPA’s use a high efficiency switching power supply. The DC power, regulation, and bias circuitry are all optimized to minimize generation of waste heat.
Remote Control
The standard unit contains one summary fault output and serial I/O to allow control and monitoring of the SSPA from a remote location. The 10-pin serial interface can be connected to RS-232 unbalanced, RS-422 balanced, or RS-485 multidrop interfaces. Baud rates are selectable from 300, 1,200, 2,400, 4,800, 9,600, 14,400, 19,200 or 28,800 baud. Unit addresses can be set between 0 and 255. Features controlled and monitored remotely include:

Operator Interface
Microprocessor-based monitor and control simplifies amplifier operation and allows incorporation of powerful user-friendly features, such as direct-reading RF power metering with display in dBm, dBW, or watts. Operation is menu-driven, with simple, logical
menus arranged in order of most frequent use. Four menu softkeys are used to scroll through menus and make selections, while two keys are used to increment or decrement parameters. Information is presented on an alphanumeric 2-line by 20-character backlit liquid-crystal display.
Fault Monitoring and Metering
The internal microprocessor continually monitors operation of the SSPA and reports any faults on the front panel display. Monitored parameters include microprocessor status, over-temperature shutdown, heatsink temperature, device currents, power supply voltages, RF output level, 1:1 status (with Option 4), maintenance switch position (with System Option A), and reflected power (with System Option B).
Nominal values and tolerances are all adjustable from the front panel via the setup menu. Password protection can be activated to prevent inadvertent or unauthorized access. Faults are reported as either major (disabling) or minor (informational). Major faults will cause automatic switchover in a 1:1 redundant system, but minor faults will not.
This VertexRSI Red. Outdoor SSPA System, 40W, model PKO14S030N is ready for sale. The system was used on a VertexRSI 3.8m Earth Station Antenna and has been used a spare back-up system. We will perform a final test before release.
