A millimeter wave vokage-controlled oscillator (VCO) MMIC was designed and fabricated with 0. 18um GaAs PHEMT process. The VCO employs reflective structure, and is optimized at frequency band of local multipoint distribution service (LMDS) in China. The chip was fabricated with OMMIC ED02AH process. Its the size is 1.2mm × 0. 8mm. The measured output power of the MMIC VCO is 7.3dBm, the phase noise is - 101 dBc/Hz@ 1MHz at 28.46GHz, and the tuning range is 27. 5 - 30. 4GHz.
