Abstract :
A novel microwave feedback oscillator utilizing the advantages of the "double-sided MIC" is proposed. The oscillator is formed incorporating microstrip lines on a dielectric substrate and CPW on a reverse side with no via holes. The fabricated and demonstrated oscillator exhibits an output power of 9.17 dBm and the harmonic suppression is -45 dBc at X-band. The phase noise performance is 114.5 dBc/Hz at the offset frequency of 1 MHz. Voltage controlled oscillators and sub-harmonic injection locked oscillators can be easily realized up to the millimeter wave band.
