发明名称 METHOD FOR TUNING A SUMMING NETWORK OF A BASE STATION, AND A BANDPASS FILTER
摘要 The present invention relates to a method for tuning a summing network of a base station, which summing network consists of connectors, conductors and a filtering means (20, 20') which include input connectors (7) for receiving signals supplied by radio transmitters (TRX1-TRX3) of the base station, and output connectors (8) for feeding the filtered signals further to an antenna means (ANT). For an easy and fast tuning of the summing network, the electric length of an output connector (8) of the filtering means (20) in the summing network is adjusted. The invention further relates to a bandpass filter (20).
