| 摘要 |
The invention relates to a surface acoustic wave (SAW) filter of the reactan ce filter type comprising at least two SAW resonators (R2, R3) in two parallel branches and comprising a SAW resonator (R1) in a serial branch. According t o the invention, an electric connection, said connection being produced on the substrate, of the ground sides (12-6, 12-7) of both SAW resonators (R2, R3) in the parallel branches is provided before the connection (12-5) to the housin g in order to be able to shift the pole location associated with the parallel branch to a lower frequency.
