ABSTRACT:
Proposed is a SAW HF filter with reactance elements, which is particularly suitable for mobile radio. The filter is balanced on both sides, is electrically symmetric, and comprises a four-pole reactance series element, which can be formed from two two-pole pole reactance elements or from a four-pole reactance element, and a resonator. One bar of the respective reactance elements is connected to the input side of the filter, while the other bar is connected to the output side of the filter.
