Abstract : The invention comprehends a non-linear amplifier circuit which together with a multimode oscillator provides a stable comb spectrum generator or alternatively, a stable rf pulse generator. The non-linear amplifier circuit includes a transistor amplifier with the supply voltage reduced to a critical range, typically about 4 V. The circuit parameters in conjunction with the transistor, are selected such that the average input threshold level, above which an output response occurs, increases with increasing pulse amplitude. The circuit is designed so that the time constant for the threshold level exceeds the pulse repetition period. It is also designed so that the value of small signal gain of the repressed amplifier allows the oscillator to be self-starting under all conditions. (Author)
