Abstract : The report describes the design and testing of X-band TRAPATT oscillators and amplifiers. The amplifier circuits were designed to permit, in principle, broadband output by prohibiting 'time-delayed triggering.' A circuit of this type was fabricated and performed with 150 MHz bandwidth at 8.0 GHz. X-band oscillators were fabricated with careful attention paid to reduction of ohmic losses and enhancement in their ease of triggering. Several devices were found which would oscillate at greater than 30% efficiency (one over 40%) at X-band frequencies. (Author)
