Abstract:
An arrangement for frequency-selective suppression of high frequency signals at undesired signal frequencies within a transmitting device, a receiving device or a transmitting and receiving device, said arrangement comprisinga common substrate plate (1);separate substrate faces (2,3) spaced from each other on the common substrate plate (1);a hood (6) disposed on or above said common substrate plate (1) to form a hollow chamber (11) between said hood (6) and said common substrate plate (1), said hollow chamber being bounded by electrically conductive walls;respective coupling terminals (4, 5) for coupling the high frequency signals into and out of the hollow chamber (11), said respective coupling terminals (4,5) being radiator elements embodied by respective striplings and said hood (6) being arranged on said substrate plate (1) to cover said radiator elements;wherein one of said radiator elements is connected with said transmitting device, said receiving device or said transmitting and receiving device to couple said high frequency signals into the hollow chamber and another of said radiator elements is connected with said transmitting device, said receiving device or said transmitting and receiving device to couple said high frequency signals out of said hollow chamber.
