摘要

提出了一种可实现高输出功率、低谐波和低相位噪声的振荡器无源缓冲器。采用InGaP/GaAs HBT技术制作了无源缓冲器交叉耦合振荡器。振荡频率为6.96 GHz。在单侧输出功率9.43 dBm时，二次谐波抑制为-36.23dBc。在1MHz偏移时相位噪声为-121.33 dBc/Hz。芯片尺寸为0.81 × 0.63 mm2。并将其性能与先前报道的振子进行了比较

A C-Band Oscillator MMIC with High Output Power, Low Harmonics, and Low Phase Noise using Passive Buffer

A passive buffer of an oscillator to obtain high output power, low harmonics and low phase noise is presented. A cross-coupled oscillator with the passive buffer is fabricated using InGaP/GaAs HBT technology. The oscillation frequency is 6.96 GHz. The 2nd harmonic suppression is -36.23dBc in the one-side output power 9.43 dBm. The phase noise is -121.33 dBc/Hz at 1MHz offset. The chip size is 0.81 times 0.63 mm2. The performances are compared with those of the previously reported oscillators
