Ultra-waveband Components


[ Ultra-wideband balun ]	[ Cross-sections and field ]

Ultra-wideband components are constructed using a novel uniplanar ultra-wideband balun, which has been developed and patented by our company in 2007.

This balun is a structure which converts signals from a microstrip line (unbalanced line) to a coplanar strip line (CPS; balanced line). The balun has proved its ultra-wideband operating frequency range from DC to over 40 GHz. Utilizing this balun, our company is currently developing a variety of ultra-wideband components with 10s of GHz bandwidth,

including double-balanced mixers, frequency doublers, detectors, antennas, and other modules which integrates the UWB components.

Thanks to excellent properties of this new balun, our ultra-wideband components have equal or better performance as compared with the conventional ultra-wideband balun products, but the component implementation cost can be much lower.
