摘要：
Techniques are described for protecting an implantable medical device (IMD) from effects caused by interfering radiated fields. An IMD incorporating these techniques may include a telemetry conduction path that includes a first end electrically coupled to a telemetry antenna and a second end electrically coupled to a telemetry circuit disposed within a housing of the IMD. The IMD may further include a stub filter electrically coupled to the telemetry conduction path and configured to attenuate an interfering signal induced in the telemetry conduction path. The stub filter may include a dielectric and a conductor disposed within the dielectric. The conductor may include a first end electrically coupled to the telemetry conduction path and a second end configured in an open circuit configuration. The conductor may have an electrical length approximately equal to one-quarter wavelength of the interfering signal when propagating through the stub filter.
