A poor man's TRAPATT oscillator

A Fairchild FD-300 diode has been made to operate in the TRAPATT mode of oscillation in an inexpensive circuit constructed of commercially available RF components. The best performance achieved was a pulsed output of 68 watts at 630 MHz with an efficiency of 12 percent. Since the diodes are inexpensive and readily available and the mount used was simple to construct, it is felt that this information will open this interesting area of research to those with limited budgets.
