高速多媒体数据通信需求的飞速增长，推动无线传输数据速率达到2Gbps以上。在这些高速数据通信系统中，误码率（BER）特性取决于压控振荡器的相位噪声性能。为了应对上述挑战，这些系统需要具有低相位噪声、低成本、宽调谐范围和高dc - rf转换效率的高性能压控振荡器。使用SWR（慢波谐振器）和模式耦合技术开发的微型压控振荡器支持高dc - rf转换效率和低相位噪声，尺寸紧凑，并且易于集成到IC（集成电路）形式。在多模式下使用慢波动力学，从12 GHz载波测量到的10 kHz偏置的典型相位噪声为- 110 dBc/ Hz，电压为5V，直流偏置为30 mA。
Demands for high-speed multimedia data communications increasing telescopically, pushing wireless transmission data rate with 2Gbps or higher. In these highspeed data communication systems, the bit error rate (BER) characteristic is dependent on a phase noise performance of the VCO. To meet the above challenges, it is necessary for these systems to have high performance VCO with low phase noise, low cost, wide tuning range, and high DC-to-RF conversion efficiency. The tiny VCO developed using SWR (Slow Wave Resonator) and mode-coupling techniques support high DC-to-RF conversion efficiency and low phase noise in compact size and also easily amenable for integration in the IC (integrated circuit) form. The typical measured phase noise @ 10 kHz offset from the 12 GHz carrier is −110 dBc/ Hz with 5V, 30 mA DC bias using slow wave dynamics in multi-mode regimes.
