Abstract
The present invention relates to a DC extracting arrangement in a RF filter 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. The invention also relates to a filter housing made from Zinc or Zinc alloy.
