Abstract :
A Ka-band monolithic microwave integrated circuit (MMIC) oscillator was implemented by using a coplanar waveguide photonic bandgap (PBG) resonator and a 0.1-μm GaAs pseudomorphic high electron mobility transistor. A coplanar labyrinthine one-dimensional PBG resonator was used for reduction in MMIC size. The fabricated MMIC oscillator had an output power of 6.5dBm at 30.3GHz and a free-running phase noise of -80dBc/Hz at 100-kHz offset.
