Xicom XTD-400K 400W Antenna Mount Ku-Band TWTA
The XTD-400 is a compact self contained antenna mountable high power amplifier (HPA) designed for low cost installation and long life. The outdoor design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and the antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self contained within the HPA. These features provide high reliability, low maintenance costs, and low replacement costs.
- No Shelter Required
- Short Waveguide Run
- Power Factor Corrected
- High Efficiency Dual-Stage TWTs
- Complete RS-232/422/ 485 Interface
The XTD-400 uses high efficiency dual-stage collector Traveling Wave Tubes (TWT). Some benefits of this type of TWT 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-400 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 (100 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-400 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 supplied to mount the HPA to most popular antennas.
