2. The resonance network is connected to the gate , then the output and input matching network is designed to satisfy the oscillation criteria . then harmonic balance method is used to analysize and optimize the output power and phase noise . to minimize the load pulling effect a buffer amplifier is designed to isolate the oscillator and the load
   本文在场效应管fet栅极上加上谐振网络(谐振网络是通过cst仿真得到的,它是串联反馈回路,介质工作在te01模,对于其后的fet ,它又相当于一个带阻滤波器) ,然后设计输入输出匹配电路,使电路结构满足起振条件,之后继续用谐波平衡法仿真和优化,使振荡器输出功率合适,相位噪声很低。

百科释义

Load-pull is the colloquial term applied to the process of systematically varying the impedance presented to a device under test (DUT), most often a transistor, to assess its performance and the associated conditions to deliver that performance in a network. While load-pull itself implies impedance variation at the load port, impedance can also be varied at any of the ports of the DUT, most often at the source.
