The Xicom XTD-750K is a compact, self-contained, antenna mountable power amplifier designed for low cost installation and long life. |
The XTD-750 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-750 uses high efficiency, dualstage collector Traveling Wave Tubes (TWT). Some benefits of this type of tube are:
- Reduced prime power consumption
- Lower internal operating temperatures
- Reliability enhancement
These benefits are obtained for both the linear and saturated modes of operation.
The XTD-750 incorporates power factor correction circuitry, which minimizes line current distortion and reduces the required Volt-Amps. The combination 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).
