Abstract :
A non-deterministic pulse technique for pulsed oscillating amplifiers is presented. Using random pulse width modulation (RPWM) for switching the injection-locked oscillator, its discrete harmonics are spread. Measured results show that discrete harmonics are reduced by 60 dB, which greatly reduces the filtering required for these harmonics.
