Latest Patents
Ichikawa's latest patents include innovative designs for a diplexer and a multiplexer. The diplexer he developed provides a high degree of design freedom, allowing for the realization of desired electric characteristics while also enabling downsizing. This diplexer features a filter with a first pass band and a second pass band, where the frequency band of the second pass band is at least twice as high as that of the first. The first pass band filter is of the lumped constant type, while the second pass band filter is of the distributed constant type.
Additionally, he has patented a laminate type band pass filter that can generate an additional attenuation pole without the need for an extra attenuation circuit. This innovation improves the attenuation characteristics of the laminate type band pass filter by allowing independent control of the frequencies of the attenuation poles. The filter includes multiple first resonators arranged in a laminate, which are mutually electromagnetic field coupled.
