Ceramic microwave filter having greater edge steepness |
摘要 |
The invention relates to a ceramic microwave filter having an insertion loss characteristic curve with an improved steepness. At least two resonators are provided in a one-piece ceramic body and coupling structures are assigned to the resonators for capacitively coupling the ceramic filter to an external RF circuit. At least one counter-oscillator is led in parallel with the resonators in the ceramic body.
