| 摘要 |
The invention relates to a high-frequency bandpass filter comprising at least one parallel resonator stage formed by an inductive component (L1-L5) and a capacitive component (VD1-VD6) connected in parallel with it. The invention provides a filter which is adjustable within a wide frequency range and which can be mounted without mechanical tuning, the filter being characterized in that the inductive component is formed by a generally U-shaped microstrip pattern (1, 2, 3) on a circuit board. |
