[United: The frequency coverage of the company’s vector network analyzer is up to 9GHz It does not yet have the testing capabilities required to report the application scenario] On September 23, Unilever (688628.SH) issued an announcement of abnormal stock trading fluctuations. The company noticed that vector network analyzers have attracted a lot of attention in the market recently. Related reports mentioned that "as data center networks are accelerating the evolution to 800G and 1.6T, high-speed connectors, cables and high-end PCBs continue to increase the requirements for signal integrity and yield control, driving the growth in VNA testing demand." The company has verified that vector network analyzers in this type of application scenario have high requirements for working frequency coverage indicators, usually requiring frequency band capabilities of 67GHz and above; the company's product frequency coverage range is up to 9GHz, and it does not yet have the testing capabilities required for the above application scenarios.
