The XTU750 is a compact, selfcontained, antenna mountable power amplifier designed for low cost installation and long life. The XTU750 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 selfcontained within the High Power Amplifier (HPA). These features provide high reliability, low maintenance costs, and low replacement costs.

The XTU750 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 XTU750 incorporates power factor correction circuitry, which minimizes line current distortion and reduces the required VoltAmps. The combination of power factor correction and high efficiency TWTs reduces input VoltAmps 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 XTU750 may be configured for single thread, redundant, phasecombined, or linearized operation.

A remote external controller is available to operate the HPA from a user selected location. Mounting brackets can be supplied to mount the HPA to most popular antennas.
