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.
