Measuring Instrument Makers Set Sights on Higher-Frequency Bands

In 2022, the measuring instruments industry saw an increase in demand thanks to the robust semiconductor market accompanying the advancement of internet of things (IoT) and digitization. Also, the increase in demand for measuring instruments finds support from the development and production expansion of electric vehicles (EVs) to achieve carbon neutrality.

Full Use of mmWave Frequency Bands

In terms of fifth-generation (5G) communication system, full-scale investments in the development of low-frequency bands, such as Sub-6 band with frequency lower than 6GHz, is notable. From now on, investments on the development and production of high-frequency bands or millimeter wave (mmWave) get into full swing. By the end of FY2025, allocation of additional frequency bands, including mmWave bands, such as 26GHz and 40GHz bands, will be implemented for 5G.

Moreover, use of 5G expands into a wide range of fields. Among them include smart factories using local 5G, autonomous driving and advanced driver-assistance systems (ADAS) for automobiles, and IoT. This trend will generate new demand for measuring instruments.  

5G-Advanced and next-generation 6G are seen for commercial adoption around 2030. Amid the spread of metaverse and digital twins, 6G communication infrastructure has become indispensable.

Measurement technologies support tech companies develop semiconductor and information communication technologies targeting large-capacity communication using terahertz frequency bands.  

Moreover, the digitization of society dramatically increases the amount of data distribution. Achieving high-speed, large-capacity communication infrastructure and data centers is an urgent issue.  

Hyperscalers or large-scale operators are leading the installation of ultrahigh optical communication networks of 800 Gigabit Ethernet (GbE). This is an upgrade from the existing 100GbE and 200GbE. Data centers will use next-generation network testers.

SiC, GaN Power Devices

In the area of semiconductors, the demand for next-generation power devices, such as silicon carbide (SiC) and gallium nitride (GaN), is taking off. These new power devices excel in high temperature resistance. Also, they feature excellent high voltage and high current characteristics and significantly reduce power loss. Measuring instruments are used to evaluate power devices that achieve lighter, smaller, energy efficient and high efficiency modules. Specifically, these tools feature higher band and high-speed sampling to capture high-speed signals. 

Moreover, mass production of the third-generation gallium oxide (Ga2O3) came in sight. Makers of measuring instruments support the evaluation of these power semiconductors.

In 2023, the demand for measuring instruments and sensors installed in various semiconductor manufacturing processes will likely increase.  

Furthermore, in the power electronics field, higher power efficiency is pursued. In relation, inquiries for measuring instruments for the evaluation of three-phase motors and other power devices continue to increase.

Measurement systems combined with various sensors are used for the inspection of equipment and surveillance of aging infrastructure. As labor shortage is a serious issue regardless of industry type, these solutions can enhance efficiency of maintenance work. Moreover, measuring instruments manufacturers are coming up with solutions to remotely monitor equipment and infrastructure by combining them with communication networks.
