[China Instrument Network Instrument Development] Recently, 203 successfully developed a microwave millimeter wave high-speed frequency conversion signal generator, the frequency range covers 10MHz ~ 67GHz, frequency agility and speed agility less than 95 nanoseconds, the overall technical indicators have reached abroad The advanced level of similar products.
At present, the universal frequency conversion frequency source at home and abroad generally has the function of frequency agility, frequency agility time is about 200 nanoseconds, and it has a simple frequency modulation and amplitude modulation function. However, foreign countries strictly restrict the introduction of broadband agile frequency synthesizer products in China, and such products are expensive. The successful development of this project will play an important role in breaking the foreign monopoly and blockade of technology and achieving localization.
This product breaks through key technologies such as high-speed broadband frequency agility, high-speed power agility, and precise timing synchronization. It utilizes high-speed digital devices and modern digital signal processing technologies to generate broadband, high-speed, agile baseband signals that not only can quickly produce low clutter and low Phase noise single-frequency signal, but also can produce broadband linear frequency modulation signal and vector signal. This product has a good comprehensive index, and it can maintain the low clutter and low phase noise of the signal while achieving the agility of the wideband frequency. It can be widely used in radar detection, electronic countermeasures, navigation and positioning, precision guidance and other tests, and has good Economic and social benefits.
With the full implementation of “Made in China 2025â€, 203 Institute, as a research institute based on measurement testing technology, is increasing the research and development of products in the basic technology field to solve the “cracker†problem and enhance the development of China’s military industry. stamina. According to Li Hongyu, the person in charge of the project, 203 has a sound frequency synthesis technology foundation, and after more than 10 years of painstaking research, 203 frequency synthesizer technology levels have been continuously improved, in the frequency of agile synthesis, low noise frequency synthesis, phase noise can be adjusted Frequency synthesis, wideband complex modulation frequency synthesis and other frequency synthesis technologies have formed their own professional characteristics and expertise. In the future, 203 will continue to follow the development trend of frequency synthesis technology, continuously improve the level of frequency synthesis technology, develop more frequency source products with distinctive features and high levels to meet market demands, and take the path of characteristic and differentiated product development.
