Several tasks were active during this report period: (1) noise modulation in avalanche-diode devices; (2) schottky-barrier microwave devices; (3) intermodulation products in IMPATT diode amplifiers; (4) harmonic generation using Read-diode varactors; and (5) fabrication of GaAs Schottky-barrier IMPATT diodes.
Self consistent one dimensional large signal analysis of Read type IMPATT diode oscillator, taking into account device-circuit interaction
A model for an injection-locked IMPATT diode oscillator is presented and used to calculate the locking behavior of the oscillator at different operating points. The model is compared with earlier theories of injection locking in IMPATT diode oscillators and the calculated results are compared with experimental observations.
