摘要
研制了一种基于基片集成波导的W波段平面注入锁定谐波振荡器.为了获得大的注入功率,注入锁定谐波振荡器采用基波端口强耦合结构,利用谐波提取技术的频率倍频作用,自由振荡输出频率在90.2 GHz附近.当基波注入信号在45.08 GHz附近时,锁定带宽大于120 MHz,输出功率大于6.5 dBm.将该平面集成的注入锁定谐波振荡器与低频参考信号同步,能够产生稳定的W波段低相噪信号.
A W-band planar injection-locked harmonic oscillator （ILHO） based on substrate integrated waveguide （SIW） was implemented. Using the technique of harmonic extraction from diodes as a frequency multiplier, this ILHO has a free- running output frequency around 90. 2 GHz under the condition of strong coupling for high injection power. When injecting a signal near 45.08 GHz in the fundamental injection-locked mode, it has an output power more than 6. 5 dBm with a loc- king bandwidth of more than 120 MHz. The combination of the simple synchronization with a low-frequency reference signal allows the generation of stable and low phase-noise W-band signals with a fully integrated planar source.
