Abstract

A standard Substrate Integrated Waveguide (SIW) based bandpass filter (BPF) suffers from bulkiness that limits its application in the implementation of compact size low phase noise oscillator. Instead, in this paper, an eighth mode SIW (EMSIW) resonator based BPF is utilized to realize a miniaturized low phase noise oscillator for X-band applications. Additionally, an equivalent circuit model of EMSIW-BPF is presented. A compact feedback type oscillator prototype using EMSIW-BPF is designed and fabricated for the first time with a circuit area of just only 1092 mm2. The experimental results of the prototype show a phase noise of -126.13 dBc/Hz at 1 MHz offset from 9.97 GHz oscillation frequency with an output power of 3.17 dBm.
