Finally, detailed experimental results are given. The test results show that the RF chip of satellite navigation receiver has the characteristics of low noise, low power consumption and multi-mode compatibility. RF receiver and baseband processing module are successfully docked, and good navigation and positioning effect is achieved. With the development of CMOS RF technology, the research focus of RF IC is gradually turning to the design of low frequency medical chip and high frequency segment, low power consumption and high integration RF chip. Based on the research of low-noise amplifier, mixer, voltage-controlled oscillator, high-speed pre-divider and other key RF circuit modules in dual-channel multi-mode satellite navigation RF receiver chip, the low noise mixer, self-oscillation mixer, and so on, are studied in this paper. In this paper, low noise self-oscillation mixer and other current research hotspots of RF circuit are deeply studied, and the design and realization of X-band RF front-end module in CMOS process are explored. Based on the above research, this paper designs a new low-noise self-oscillation mixer using current multiplexing technology, and analyzes the key design parameters of low-noise self-oscillation mixer, such as conversion gain, noise figure, phase noise, etc. The circuit is designed in detail. Finally, the layout design and test results of low noise self-oscillation mixer are given.
