|The Xicom XTD-400DBL series are compact selfcontained antenna mountable power amplifiers designed for low cost installation and long life.|
The XTD-400DBL series design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and the antenna feed horn; for example, an antenna mounted 350 Watt amplifier with its shorter waveguide run will often deliver EIRP comparable to a 600 Watt rack mounted HPA. RF filters, cooling, and monitoring & control systems are all selfcontained within the HPA. These features provide high reliability, low maintenance costs, and low replacement costs.
The XTD-400DBL series incorporates high efficiency, dualstage collector TWTs. Some of the benefits of this type of TWT are: reduced prime power consumption, lower internal operating temperatures, and reliability enhancement. These benefits are obtained for both the linear and saturated modes of operation. One of the features of the XTD-400DBL series is incorporation of power factor correction circuitry that 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 (100 to 260 VAC). The automatic features of the power supply include quick recovery from prime power outages and multiple helix fault resets (three fault cycles).
A complete monitoring & control system is built into the unit. Ten status and fault monitors are provided for external monitoring.
The XTD-400DBL series can 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.
