In this paper, we have studied a high power oscillator of a high RF output power and a good phase noise. We designed the high power oscillator using LDMOS(laterally diffused metal oxide semiconductor) device by the use of an Agilent advanced design system (ADS). We also designed the rectangular cavity resonator in order to obtain a good phase noise by using(More)
The various types of atmospheric pressure plasma jets (APPJs) have been developed as the proto-type of user friend in Plasma-Bio Research Center (PBRC), Korea. According to the power sources the discharge-types are DC & a low frequency AC, RF, and micro-wave. (i) The plasma jet devices of DC-type and DBD-types have been made as the portable(More)
