[Design Examples and Technical Introduction] High-Frequency Solutions

Providing circuit boards with high simulation reproducibility by combining low dielectric loss alumina substrate manufacturing technology, high-precision patterning technology, and design and evaluation techniques.

In the millimeter wave and terahertz wave regions used in Beyond 5G (6G), low-loss substrate characteristics and fine patterning technology are required. In addition to the manufacturing technology of low dielectric loss ceramic substrates that we have cultivated over many years, high-precision patterning technology, and design technology that meets customer requests, we have also become capable of simulation and measurement at high frequencies. As a result, we can provide high-frequency circuit substrates with high reproducibility in simulations. Please feel free to consult us with any requests or questions, such as "I want this kind of passive component." We will solve problems with our technological development capabilities and comprehensive strength that only a substrate manufacturer can provide.

basic information

【Design and Evaluation Technology】 We have a proven track record in design and evaluation in the 26GHz and 40GHz bands used in 5G. Beyond 5G (6G), frequencies above 100GHz and even higher terahertz waves will be utilized. Using material technology, processing technology, simulation technology, and measurement technology, we provide low-loss devices that meet customer requirements in this frequency range. 【Substrate Materials】 We offer a wide range of materials from low dielectric constant to high dielectric constant. The dielectric loss tangent is also low, with 99.9% alumina being a very low-loss material with values around 10^-5 in the several tens of GHz range. 【Patterning Technology】 We offer a wide range of materials from low dielectric constant to high dielectric constant. The dielectric loss tangent is also low, with 99.9% alumina being a very low-loss material with values around 10^-5 in the several tens of GHz range.
