Analysis of oscillation-starting characteristics in millimeter wave extended interaction oscillators
摘要
Abstract
The investigations of the oscillation-starting characteristics of a ladder-type RF circuit are proposed toovercome the limitation of high ohmic loss for development of millimeter-wave extended interaction oscillators (EIOs). Based on PIC-simulations,quantitative calculations and theoretical analyses,the designed and fabricat-ed W-band EIO is proved to have the possibility of greatly reducing the oscillation-starting current. By optimizing five aspects including the gap number,cavity dimension,field distribution,operation voltage,and surface loss, the oscillation-starting current of the EIO can be reduced to 0. 43 A with a beam voltage of 17. 5 kV. According to cold test experiment,the output power attenuation is analyzed and predicted.关键词
