Focus on terahertz testing to boost national technological innovation
[ Instrument Network Instrument Development ] Terahertz technology has been hailed as one of the top ten technologies that have changed the world and is popular all over the world. In the country, the terahertz Xiangshan Conference was held in 2005, and the research direction of terahertz technology was established, which triggered a craze for national terahertz technology research. Terahertz test technology is the pioneer of terahertz technology research and one of the bottlenecks of terahertz technology research, which restricts the rapid development of terahertz technology in China.
CLP terahertz test R & D team
The terahertz test is a pioneering technical field with a step-by-step approach. It faces many problems in researching new mechanisms, exploring new materials, breaking through processes, etc., which makes terahertz testing once the core technology of the technology powerhouse, while domestic due to electronic components. The basic technology and other aspects are lagging behind in foreign countries. It is necessary to develop high-precision terahertz test conditions, and the domestic difficulties are even greater. CLP Instrument and Meter Co., Ltd. (hereinafter referred to as “Zhongdian Instrumentâ€) has a strategic layout. Established a professional team and shouldered the mission of our terahertz test.
Faced with a near-zero basis, CLP's terahertz test R&D team is not afraid of challenges, bravely shouldering heavy burdens, based on domestic industrial basic conditions, core design and manufacturing, circuit modeling, precision manufacturing, metrology and calibration. The technology has carried out a comprehensive research: the ridge waveguide spatial multi-frequency multiplication method has effectively improved the compression point of the frequency multiplier, eliminating the influence of device parasitic parameters and electrical length, and solving the wide frequency band and high efficiency of the traditional frequency doubling circuit. The contradiction between the two has effectively improved the wideband output power of the frequency multiplier; established a balanced-to-unbalanced conversion circuit model of the all-metal structure, effectively reducing the dielectric loss, greatly expanding the bandwidth of the frequency multiplier, and improving the frequency multiplication efficiency. The result is that the frequency doubling efficiency is greater than 10% in the full waveguide bandwidth; the terahertz power meter is realized by the detection scheme, which solves the problem of fast response and high sensitivity detection of the terahertz signal, and overcomes the international thermocouple terahertz power meter. Problems such as large environmental impact, small power detection range, and slow detection speed; using terahertz heterogeneous circuit integration technology, eliminating Uniformity of terahertz hybrid integrated circuits and large insertion loss of traditional terahertz single crystal integrated circuits; realization of 50GHz to 500GHz series of high performance millimeter wave and terahertz vector network analyzers, spectrum analyzers, signal generators and power With four kinds of measuring instruments, the comprehensive performance has reached the international advanced technology level.
