Pulsed-waveform generator based on coupled oscillators

摘要

Waveform sharpening in nonlinear transmissionlines (NLTL) is analyzed in detail and applied to the design of apulse-generator based on two coupled oscillators. The maximumpropagation frequency through the NLTL is calculated with arealistic numerical technique, which enables an optimized design.By coupling two NLTL oscillators terminated in grounded stubsof different length, three design parameters are available, whichenables a flexible mechanism for pulse formation. A reducedordermodel is proposed for the efficient determination of thetuning voltage in one of the oscillator elements. The analysis anddesign techniques have been applied to a prototype at 0.8 GHz.
