Product Code: XTD-250KaL

The XTD-250Ka-B1 series are compact, self contained antenna mount power amplifiers designed for low cost installation and long life. Cooling and monitor & control systems are all self contained within the amplifier. By combining the power supply and the RF components within the same amplifier case the need for external high voltage cables (required for split box designs) is eliminated. This highly compact unit typically weighs only 46 lbs.

This series of amplifiers provides several methods of tube protection. Due to Xicom’s unique power supply design less than 1 joule is stored in the power supply. A high frequency resonant conversion power supply is used that accepts a wide range of prime power (90 to 264 VAC).

The unit also features power factor correction circuitry that minimizes line current distortion and reduces the required volt-amps input. This amplifier has built-in waveguide switch control capability. This can be used in a 1:1 redundancy configuration. A single RS-485 cable can control two amplifiers and redundancy switch. The amplifiers are available with multiple options including redundant and phase combined system configurations, integral linearizers and harmonic filters. Remote external controllers are available to operate the HPA from a user selected location.
