摘要： The present invention is an electronic isolator that provides low input to output insertion loss, high output to input insertion loss, and substantial asymmetric isolation between a source circuit and a load circuit. The invention actively reduces noise and reflected power appearing on the isolator output. In numerous embodiments, the invention operates in circuit applications from dc through millimeter wave. Multistage electronic isolator embodiments provide increased isolation and greater noise reduction. In other embodiments, the electronic isolator also removes noise appearing on its input. In another embodiment, the invention is configured for high power applications. This embodiment includes circuitry for redirecting power away from the load into resistors or other dissipative elements. In another embodiment, the electronic isolator is configured to remove signal distortion produced by one or more power amplifiers in the system.
摘要翻译：本发明是一种电子隔离器，其提供低输入到输出插入损耗，高输出到输入插入损耗以及源电路和负载电路之间的实质上的非对称隔离。本发明主动地减少隔离器输出上出现的噪声和反射功率。在许多实施例中，本发明在从直流到毫米波的电路应用中工作。多级电子隔离器实施例提供增加的隔离和更大的降噪。在其他实施例中，电子隔离器还消除其输入上出现的噪声。在另一个实施例中，本发明被配置用于大功率应用。该实施例包括用于将功率从负载重定向到电阻器或其它耗散元件的电路。在另一个实施例中，电子隔离器被配置为去除系统中由一个或多个功率放大器产生的信号失真。
