Patents by Inventor Martin Bünner

Martin Bünner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Circuit with reduced insertion loss and component comprising one such circuit
    Patent number: 7583936
    Abstract: An electrical circuit has at least two parallel signal paths connected to one another on the antenna side and for which a band reject filter corresponding to the transmission range is implemented in a second signal path for frequency-selective improvement of insertion loss in the transmission range of a first signal path. With a band reject filter, the signal is reflected to the junction of the parallel signal paths arising from the second signal path and thus is rerouted to the first signal path.

  • Transducer structure that operates with acoustic waves
    Patent number: 7042132
    Abstract: For improved conformance of a filter operating with acoustic waves, a transducer structure is provided in which the separations between respectively two adjacent electrode fingers of an inter-digital transducer (IDTv) vary over the length of the transducer. The variation thereby preferably follows a continuous distribution function. Reactance filters that are provided with such filters in the serial branch show an improved electrical conformance in the transmission range.
