In this paper, a novel metamaterial Möbius Oscillator (MMO) is discussed, and validated with the example of 30.2 GHz frequency source for the application in 5th generation communication systems. The measured PN (phase noise) is −149dBc/Hz @ 100 kHz offset from the carrier, exhibits typically 11.6 dBm output power. The measured FOM (figure of merit) @ 1MHz is −230 dBc/Hz for a given 550mW DC power consumption (7.5V, 73 mA). To author's best of knowledge, the measured PN and FOM offers best performance at Ka-Band (26GHz–30GHz) reported to date for a given class of electronic signal sources.
