Oscillator Design and Fabrication using a Miniatured Hairpin Resonator

In this papers, an S-band oscillator of the low phase noise property using a miniaturized micro-strip hairpin shaped ring resonator is presented. The substrate has a dielectric constant εr=3.5, a thickness h=0.508 mm, and loss tangent tan δ=0.002 A designed and fabricated oscillator shows low phase noise performance of 99.71 ㏈c∕㎐ at 100 ㎑ offset frequency and of output power 19.584 ㏈m at center frequency 2.450 ㎓. This circuit was fabricated with hybrid technique, but can be fully compatible with the MMIC due to its entirely planar structure.
