Abstract : The purpose of this project was to design, develop and deliver three X-band high-power amplifier chains for use in an airborne, high resolution radar. Each chain, comprised of two Amplitron crossed-field amplifiers (QKS1243/ QKS 1244) and a ferrite isolator, produces a peak power output of 500 kilowatts at a gain of 27 db. The QKS1243/1244 amplifier chain operates at a band center frequency of 9600 Mc, its output stage, the QKS1243 Amplitron, operates in either of two modes. In one mode, it produces a power output of 500 kilowatts at 0.0014 duty cycle and, in the other, it yields 250 kilowatts at 0.0028 duty cycle. The chain test program included, as design tests, a 300 hour life test and operational vibration tests. Complete electrical acceptance tests were performed. These tests included power output and phase versus frequency, efficiency and phase sensitivity to variations of pulse current.
