提出了一种基于准MMIC技术的Ku波段宽带压控振荡器.该电路采用MMIC芯片和外加高Q值的超突变结变容管的方式,实现了覆盖整个Ku波段的超宽带的振荡信号输出.通过将MMIC技术与混合集成技术相结合的方法,大大降低了调试难度,更重要的是,克服了通用pHEMT MMIC工艺难于兼容高Q值的变容管对超宽带设计VCO的限制,在相位噪声和调谐频率线性度方面都有较大改善.该方法为微波、毫米波压控振荡器的设计提供了一个新的途径.

Using an in-house MMIC and an off-chip,high-quality varactor,a novel wide band VCO covered Ku band is introduced. In contrast to HMIC technology, this method reduces the complexity of microchip assembly. More importantly,it overcomes the constraint that the standard commercial GaAs pHEMT MMIC process is usually not compatible with high-quality varactors for VCO,and it significantly improves the phase noise and frequency tuning linearity performances compared to either MMIC or HMIC implementation. It is a novel and high-quality method to develop microwave and millimeter wave VCO.
