| 摘要 |
The present invention relates to a RF filter made from Zink or a Zink alloy, preferably used for extracting a DC voltage and/or a low frequency signal (DC/Com, signal) superimposed on a RF signal. The DC/Com, signal is extracted using a low pass filter which is arranged inside the first resonator inside the filter. Preferably, the low pass filter is a tubular filter. |
