Abstract :
A novel C-band low phase noise dual-band oscillator using a reconfigurable cavity-backed complementary split-ring resonator (CSRR) is proposed and developed based on the substrate integrated waveguide (SIW) technology. The resonator consists of a PIN diode switch and a CSRR resonator embedded in an SIW cavity. It is able to provide two different resonance frequencies by selecting different diode modes. A switchable matching stub is used for matching each of the two states. Measured results show that the proposed oscillator is able to operate at 2.675 and 3.77 GHz, respectively, with a phase noise of 105.5 and 99.6 dBc/Hz at a 100 KHz offset.
