WebCircular cavity resonator-based low phase noise oscillator. A substrate integrated waveguide (SIW), dual-mode bandpass filter (BPF) with a circular cavity is the most critical element in the design of X-band, low phase noise oscillators. The SIW circular cavity is used as a frequency stabilization element in the feedback loop. http://www-eng.lbl.gov/~shuman/NEXT/CURRENT_DESIGN/TP/FO/Lect4-Optical%20waveguides.pdf
