<p><P>PROBLEM TO BE SOLVED: To provide a high-frequency circuit, transmitting a high-frequency signal which includes a filter function of passing a high-frequency signal in a desired frequency band and greatly reducing passage of a radio wave in a certain specific frequency band, and also reduces a return amount of a radio wave that cannot be taken into consideration when designing. <P>SOLUTION: The high-frequency circuit that transmits the high-frequency signal includes the filter function that includes a consumption filter which converts the high-frequency signal into heat or optical energy and reduces passages of signals not in a first frequency band and a reflection filter which reflects a signal in a second frequency band such that the consumption filter is provided upstream from the reflection filter, and thereby passes the signal in the first frequency band to a filter rear stage and greatly attenuates passage of a signal in the second frequency band while suppressing an influence of behavior of a radio wave which cannot be taken into consideration when designing by reducing the return amount of the radio wave reflected by the reflection filter. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
