Information × Registration Number 0214U002688, 0113U001534 , R & D reports Title Development of spatially-advanced circuits of amplification and conversion of signals based on highly efficiency active devices popup.stage_title Head Vladimir G. Krizhanovski, Registration Date 24-01-2014 Organization Donetsk National University popup.description2 Improved methods of analysis of three-layer planar structure based on microstrip transmission line and slot resonators in its ground plane. In addition, a method of analysis step discontinuity in microstrip transmission line based on the interconnection between them. Studied the design Chebyshev bandpass filter , which uses a line segment with the slots in the ground layer of the microstrip lines as a rejector filter in the upper stopband as an element bandpass filter. Studied theoretically and experimentally mode class E oscillator with the output circuit with extended bandwidth. Investigated the stability of the ring oscillator HF class E. The method of designing the output load circuit power amplifier class F with compensation transistor parasitic elements and setting impedances at the harmonics. A scheme for the modulator amplifier with elimination and recovery of the carrier frequency (Kahn schematic) .
