The XTD-500Ka series are compact, self contained antenna mount power amplifiers designed for low cost installation and long life. Comtech Xicom offers both a "Peak" and CW version of this product across a range of commercial frequencies between 27.5 and 30 GHz. The CW version allows the amplifier to be safely driven up to its saturated power output level. The more economical Peak version is limited to operation up to its "linear" power level, which still delivers the equivalent useable multi-carrier RF power.
