Latest Patents

Roeland Heijna holds a patent for a "Filter circuit with a notch filter." This invention comprises a signal line featuring a band filter (BF) that allows a useful frequency band to pass through. Additionally, it includes a notch filter (NF) connected in series with the band filter to filter out a specific stop band frequency. The notch filter consists of a series circuit of several parallel shunt elements (SE... SE), each shifted in frequency against the others, distributing their frequencies (f... F) over a notch band. All shunt elements can be realized as a SAW one-port resonator (TR), incorporating regions with varying pitches. This innovative design enhances the efficiency and effectiveness of filtering unwanted frequencies.
