Abstract :
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
