An X-band Low Phase Noise MMIC Oscillator Using a Planar-Type MMIC Resonator
Abstract
In this paper an X-band low phase noise HBT oscillator using a planar type MMIC resonator is designed. The chip area of the proposed resonator shows a quarter of the conventional hair-pin resonator using distributed transmission lines. The measurement results show oscillation frequency of 8.295 GHz, the power output of 4.8 dBm, and phase noise characteristic of -106.8 dBc/Hz and -121.7 dBc/Hz at 100 kHz and 1 MHz offset frequencies respectively.
