20090002101 | HIGH-PASS FILTER - A high frequency filter for filtering a frequency component from a high frequency signal includes a capacitor and a branch line. The capacitor may be disposed in series to a transmission line. The transmission line transmits the high frequency signal. The capacitor performs as capacitive component to the high frequency signal. The branch line may intersect the transmission line. The branch line may include, but is not limited to, a capacitive portion and an inductive portion. The capacitive portion performs as capacitive component to the high frequency signal. The inductive portion performs as inductive component to the high frequency signal. | 01-01-2009 |
20130288609 | SELF-DIAGNOSIS CIRCUIT - A self-diagnosis circuit is coupled to a signal transmission path between a high-frequency signal input part and an output part and is configured to diagnose a high-frequency circuit using a signal that propagates along the signal transmission path. The self-diagnosis circuit includes a detector configured to detect the high-frequency signal propagating along the signal transmission path from the output part toward the input part; and a diagnosis unit that diagnoses for an abnormality in the follower stage of the high-frequency circuit disposed between a coupling part of the self-diagnosis circuit with respect to the signal transmission path and the output part, in accordance with the detection result of the detector. | 10-31-2013 |
20140368291 | INSULATION CIRCUIT AND COMMUNICATION EQUIPMENT - Disclosed is an insulation circuit comprising: a first pattern formed on a first layer of a substrate, that receives high-frequency signals; a second pattern formed on this first layer next to the first pattern and that outputs the high-frequency signals received by the first pattern; a third pattern formed on a second layer different from the first layer of the substrate and connected with a signal ground, in such a way that the first and second patterns respectively overlap in plan view; and a fourth pattern formed on the second layer next to the third pattern and connected with a frame ground, in such a way that the first and second patterns respectively overlap in plan view. | 12-18-2014 |
