Abstract :
A New IMPATT diode amplifier circuit is described which uses planar microstrip circuitry. A single-diode stage serves as a driver for a four-diode combiner stage. The combiner uses a tree of three hybrids of the Wilkinson-Gysel type. GaAs double-drift IMPATT diodes are used. The device provides a minimum of 12 dB gain over a band from 9.4 to 10.6 GHz with a peak pulsed output between 105 and 120 watts over the band.
