| Abstract(in English) | A fully monolithic K-band MMIC VCO implemented by using a 0.25μm AlGaAs/InGaAs pseudomorphic HEMT (p-HEMT) technology is presented in this paper. An easily tunable resonator is composed of a half-wavelength miniaturized hairpin-shaped resonator and a three terminal p-HEMT varactor. The use of the half-wavelength miniaturized hairpin-shaped resonator and the p-HEMT varactor is effective in reducing the chip size and simplifying fabrication processes of the MMIC. The VCO provides a typical output power of 11.5 dBm at 20.8 GHz and has a free-running phase noise of -82 dBc/Hz at 100 kHz offset and -95 dBc/Hz at 1 MHz offset. It also shows a tuning range of 70 MHz with little reduction of power. The chip size of the MMIC VCO is 1.5×2.0 mm^2. |
