Abstract :
A low cost, fully planar tunable oscillator with a low phase noise, high DC-RF conversion efficiency for C-band is presented in this work. The proposed oscillator utilizes a novel complementary coupled resonator based on substrate integrated waveguide (SIW) that has a broad tuning range of 8.84% relative bandwidth, and thereby achieves a continuous tuning oscillation range from 4.85 GHz to 5.1 GHz, or a 5.15% relative bandwidth of the proposed tunable oscillator with a low phase noise of -115.2 dBc/Hz and a DC-RF conversion efficiency of 19%.
