ABSTRACT:
A Compact Reduced Parasitic Resonant Frequency Pulsed Power Source at Microwave Frequencies is disclosed which uses a series of stacked IMPATT diodes with thick metallic heat sinks interposed between each of the IMPATT diodes with the effective heat sink of each heat sink being roughly equivalent to the diode radius in length. The effective heat sink length is matched through the disclosed analysis to the effective heat sink of the base heat sink which is located at the bottom of the stack of IMPATT diodes. The diodes are operated in a pulsed fashion and the effective heat sink length is matched to the effective heat sink of the base heat sink that the temperature of the stacked IMPATT diodes track together in time.
