The XTD-750K is a series compact, self-contained, antenna mountable power amplifiers designed for low cost installation and long life. The XTD- 750K design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self-contained within the High Power Amplifier (HPA). These features provide high reliability, low maintenance costs, and low replacement costs.
The XTD-750K uses high efficiency, dual-stage collector Traveling Wave Tubes (TWT). Some benefits of this type of tube are: reduced prime power con¬sumption., lower internal operating temperatures., and reliability enhancement. These benefits are obtained for both the linear and saturated modes of opera-tion.
The XTD-750K incorporates power factor correction circuitry, which minimizes line current distortion and reduces the required Volt-Amps. The com¬bination of power factor correction and high efficiency TWTs reduces input Volt-Amps by 45% when compared to equivalent amplifiers. A high frequency resonant conversion power supply is used that accepts a wide range of prime power (180 to 260 VAC). The automatic features of the power supply include quick recovery from prime power outages and multiple helix arc fault resets (three fault cycles). A complete serial M&C system is built into the unit.
The XTD-750K may be configured for single thread, redundant, phase-combined, or linearized operation. A remote external controller is available to operate the HPA from a user selected location. Mounting brackets can be sup¬plied to mount the HPA to most popular antennas.
