Abstract: The present invention refers to novel antihypertensive peptides which may be used as active ingredients in pharmaceutical preparations, dietary supplements, or as food ingredients.

Abstract: A transceiver 400 is provided in an ultrawide bandwidth device, which includes an antenna 110, a transmitter circuit 145, and a receiver circuit 165. A transmitter amplifier 440 is provided between the antenna 110 and the transmitter circuit 145, and is configured to have an operational transmitter output impedance when the transceiver 400 is in a transmit mode and an isolation transmitter output impedance when the transceiver 400 is in a receive mode. A receiver amplifier 460 is provided between the antenna 110 and the receiver circuit 165, and is configured to have an operational receiver input impedance when the transceiver 400 is in a receive mode and an isolation receiver input impedance when the transceiver 400 is in a transmit mode. The isolation transmitter output impedance is greater than the operational receiver input impedance, and the isolation receiver input impedance is greater than the operational transmitter output impedance.

Abstract: An integrated circuit device is provided. The integrated circuit includes an integrated circuit chip (110) having a chip input/output element (240); a packaging component (220) having a package input/output element (270); two or more connection elements (260) for connecting the chip input/output element with the package input/output element; and a protective layer (290) covering the integrated circuit chip, the two or more connection elements, and a portion of the packaging such that the package input/output element is uncovered. The two or more connection elements are configured to provide a set input/output impedance at the package input/output element. This is accomplished by considering the inductive and capacitive properties of each connection element, and selecting an appropriate number and orientation for the one or more connection elements.
