The Varian CPI VZM6990K1D is a klystron amplifier tube designed for high-frequency industrial and scientific applications. Built on decades of vacuum electron tube heritage originating from the klystron’s invention by Russell H. and Sigurd F. Varian, this amplifier delivers reliable performance in defense, communications, scientific, industrial, and medical environments. The tube features robust construction for extended operational life and efficient signal amplification across demanding test and measurement scenarios.
– Technical Specifications
Klystron amplifier tube engineered for microwave frequency operation. Related 6900K series devices operate within 1 to 18 GHz. Small signal gain typically ranges 35 to 40 dB, with saturated power gain approximately 5 dB lower. Saturated output power may exceed rated power by 6 dB or more near band center. Input and output impedance both exhibit 2.0:1 VSWR.
