The XTD-150Ka, XTD-175Ka, and XTD-250KaL 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. These highly compact units typically weigh only 48 pounds. TWTs are available delivering 120 Watts to 250 Watts in the 26.5 to 31.0 GHz band. Alternative frequency coverage is available.
