description A reactance filter, particularly in a branching circuit (ladder type),with surface wave resonators wherein omission weighted normal finger transducers are employed between reflectors such that the arrangement and plurality of the active fingers of the interdigital transducer are particularly formed for changing the capacitance relationship (static to dynamic capacitance) such that a narrow filter bandwidth is achieved.
