Along with our country based on zhongxing NO.9 live satellite "coverage", continued to promote the "promises" project and the rapid development of the global broadcast satellite industry, market demand for high frequency head is bigger and bigger, but also promote the vigorous development of the whole of the high-frequency tuner industry, more and more kinds of products, the performance requirements of more and more is also high.In recent years, with the rapid development of domestic and overseas mobile satellite receiving system industry, such as VAST, CTC, CTC, etc., the system has increasingly high requirements on the index of high-frequency head. Up to now, China telecom has obtained 5G frequency resources with a total bandwidth of 100MHz from 3400mhz-3500mhz.China mobile obtained 5G frequency resources in the bands of 2515mhz-2675mhz and 4800mhz-4900mhz.China unicom obtained 5G frequency resources of 3500mhz-3600mhz with a total bandwidth of 100MHz.More than 5 g of China telecom and China unicom spectrum with earth satellite receiving station C band 3400 MHZ to 4200 MHZ have overlap, coupled with the base station and relay equipment of all kinds of frequency doubling frequency interference, difference frequency, time, brings to the satellite earth station of radio and television signal is very large, a measure of the low noise amplifier or the inverter technology of more demanding, 5 g interference currently on the market of mature products were rare. In order to satisfy satellite TV and satellite communications in the comprehensive application requirements after 5 g business applications, hangda microelectronics rapid response to market demand, providing customers with innovative solutions, launch new products C band 5 g of LNA and LNB, effectively solve the traditional LNB in 5 g under the action of strong interference signals, satellite TV and the problem of communication cannot be applied.Hangda microelectronics 5G anti-interference LNA and LNB are suitable for c-band satellite earth stations operating at 3,700-4200mhz. The product noise temperature is less than or equal to 45K. When the input frequency is less than 3400MHz or greater than 4500MHz, the out-of-band suppression is greater than 50dB.With extremely low noise temperature and strong anti-interference ability, LNA and LNB adopt a general structural design to ensure the consistency and ease of use of the products. At present, the product design is mature and has passed the test, and all the indicators meet the expected requirements. The product quality is safe and reliable, and it can quickly meet the customized cycle of customers. |
