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.
Abstract
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 locking 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.
