摘要: A ceramic TEM resonator bandpass filter with varactor tuning is disclosed. The located within the holes of a filter, and positioned said immediately above upper extent metal plating forming in holes. placement such manner reduces interference caused by interresonator coupling. new apparatus for positioning hole disclosed basically includes conductive rod which at its top end receives varactor.
