A Millimeter-Wave Standing-Wave Oscillator With Frequency-Specific Wave-Velocity Control Demonstrating Class-F Effects 150 150

Abstract:

Implementing dual-resonance class-F oscillators with transformer feedback beyond 60 GHz poses significant challenges due to the limited third-harmonic tank impedance when using small coils with low coupling factors. To address these limitations and leverage the phase noise advantages of class-F operation, this letter introduces a standing-wave oscillator (SWO) topology featuring an …
