摘要： An enhanced loop in a passive tuner consists of an extremely low loss coupler and a high directivity circulator. In the case of source reflection factor synthesis, a passive loop generates an additional incident traveling wave. This wave, added to the primary incident traveling wave, augments the traveling wave and thus increases the magnitude of the synthesized reflection factor at the source port of a device, such as a transistor. In the case of load reflection factor synthesis, the passive loop augments the initial reflected traveling wave by pumping an additional traveling wave. This additional traveling wave helps in synthesizing a higher load reflection factor at the load port. This architecture is capable of high reflection factor synthesis that enables load synthesis even on the border of the Smith chart. There is no problem of instability with the architecture of the present invention.
摘要翻译：无源调谐器中的增强型环路由极低损耗耦合器和高方向性循环器组成。在源反射因子合成的情况下，无源环路产生附加的入射行波。加在主入射行波上的波加大了行波，从而增加了晶体管等器件的源极端的合成反射系数的大小。在负载反射因子合成的情况下，被动环通过泵浦附加的行波来增加初始反射行波。这种额外的行波有助于在负载端口合成更高的负载反射系数。该架构能够进行高反射因子合成，即使在史密斯圆图的边界也能进行负载合成。本发明的架构不存在不稳定的问题。
