Design and Optimization of Millimeter-Wave IMPATT Oscillators Using a Consistent Model for Active and Passive Circuit Parts

  • Matthias Curow

Abstract

A new CAD approach for analysis, development, and optimization of millimeter-wave oscillator circuits is presented. The method has been developed with respect to universality, accuracy, and efficiency regarding the consistent modelling of active two-terminal devices operating in passive circuits. Some benefits of the approach are demonstrated by a number of results for practically realized Si and GaAs CW IMPATT oscillators at 94 and 140 GHz. It is likely that millimeter-wave IMPATT diodes operate often in a subharmonic mode in which the fundamental power may or may not be reduced compared to a single-frequency excitation.
