[Abstract]:With the development of the aerospace industry, the development and application of satellite navigation system has become a hot research field. Satellite navigation system provides human diversity, high quality of time and location information, and the human use of these basic information can further obtain map location, direction, speed and other information, so as to solve people "when? Where?" At present, four kinds of navigation systems, such as GPS, Beidou, gilus and Galileo, have been widely used, which greatly promote the development of the mobile Internet, cloud computing and the Internet of things, and promote the development and progress of human society. This article is guided by the navigation of the Beidou, GPS, gilus and Galileo. The key technology of anti-jamming receiver chip is studied. The architecture of the receiver system, the anti jamming reconfigurable RF front end, the reconfigurable filter and the fast locking low noise phase locked loop are deeply studied. The system requirements of the navigation receiver are analyzed, and the system architecture of the reconfigurable multimode compatible navigation receiver is studied. Due to the wide frequency range of the four navigation system in the world, the design of full compatible radio frequency chip is difficult. At present, the dual channel receiver navigation RF transceiver chip has not been fully compatible. A fully compatible radio frequency chip architecture is proposed by using a reconfigurable dual channel receiver and single channel transmitter. Considering the power consumption, reconfigurability and feasibility of the system, the overall index of the multimode compatible receiver is calculated and a reasonable partition is made between the modules of the system, which lays the foundation for the research and design of each module circuit. A satellite guide covering the full band RNSS and RDSS frequency points is designed by using the SMIC 0.13 micron CMOS process. The performance of the chip test shows that the performance of the chip fully meets the needs of the signal reception of the four satellite navigation systems. In view of the interference of the wireless communication signals to the navigation system, especially the interference of the WIFI and LTE signals to the Beidou navigation system RDSS band interference, a new type of anti-interference low noise free surface wave filter is designed. The RF front end of the noise radio frequency front-end has realized the high Q value RF filter on the chip. It is the first time to realize the off band interference suppression above 18dB in the RF front end of the navigation receiver chip. The gain of the RF front end is 44.98dB at the 2.5GHz frequency point and the noise coefficient is 2.03dB, and the current type passive mixer and IIP2 are tuned to improve the linearity, thus getting up to -7d Bm's IIP3 and +72dBm IIP2. have designed a new filter circuit for the reconfiguration of low if / zero IF receiver to suppress off band interference. The filter circuit uses active RC architecture to realize the reconfigurable order, low pass / bandpass switching, compatible with the frequency points and bandwidth of various navigation systems. In all navigation system filters, The off band suppression of the 2 times of the offset center frequency is more than 38dB, and the image suppression is greater than that of the 35dB. filter. Compared with the built-in filter of other navigation chips, the filter is more than 16dB. In order to improve the compatibility of the navigation and receiving system, a new type of PLL with dual mode automatic frequency tuning function is proposed. The test results show that the AFC is only 9 Mu s, the locking time of the whole phase locked loop is 19 s, the frequency coverage range of the PLL is 2.2~5GHz, the phase noise of the phase locked loop is -90 dBc/Hz at the frequency offset 100 kHz, and the phase noise at the frequency offset 1MHz is -120 dBc/Hz. analysis of the key problems in the chip design The layout design is optimized, the channel gain, the noise coefficient and the dynamic range of the RF chip are tested and the results are analyzed and compared. The results show that the multimode receiver chip can be compatible with all navigation systems, the maximum gain of the channel is 105dB, the minimum noise number is 3.1dB, the dynamic range is 85dB, and all the navigation receivers are satisfied. This paper is supported by the project "BD2/GPS terminal equipment core chip R & D and industrialization" (2011A090200106) in Guangdong province. The research and innovation technology can be applied not only to the research and development of satellite navigation terminal equipment, but also to the research and development of the terminal equipment of his wireless communication system.
