Embodiment Construction

[0014] A multi-frequency self-adaptive wide-range up-and-down frequency conversion module, including an up-conversion module and a down-conversion module. The frequency conversion modules all have a built-in DC stabilized DC-DC power supply, which makes the frequency conversion system more adaptable. The dual-channel multi-frequency self-adaptive power consumption is less than or equal to 9 watts, which reduces the total power consumption of the whole system. The up-conversion module includes a single-chip microcomputer 1, the output of the single-chip microcomputer 1 is respectively connected to the input of the phase-locked loop 1 and the input of the phase-locked loop 2, and the phase-locked loop 1 and the phase-locked loop 2 respectively divide the frequency of the input frequency signal and lock the phase The output end of loop 1 is connected to the signal input end of the upper-stage mixer, the output end of phase-locked loop 2 is connected to the signal input end of the ...

Abstract

The invention discloses a multi-frequency-point adaptive wide-range up-down frequency conversion module, the up-conversion module and the down-conversion module are both secondary conversion and are both double-path conversion, and the up-conversion module specifically comprises a voltage stabilizer, a single chip microcomputer, a phase-locked loop, a medium frequency mixer, a radio frequency mixer, a medium filter, an amplifier and a medium frequency filter; and the down-conversion module comprises a voltage stabilizer, a single-chip microcomputer, a power divider, a phase-locked loop, an intermediate frequency mixer, a radio frequency mixer, a dielectric filter, an amplifier, a surface acoustic wave filter, an intermediate frequency filter and a radio frequency variable gain amplifier. The system is a Beidou system multi-frequency-point adaptive wide-range up-down conversion module device, and solves the problem of receiving and transmitting satellite navigation signals through single-channel multi-frequency-point switching. The system is high in compatibility, the expansibility of peripheral equipment is good, and stable anti-interference performance is achieved.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to a multi-frequency point self-adaptive wide-range up-down conversion module. Background technique [0002] The establishment of the Beidou satellite navigation and positioning system has promoted the development of my country's independent satellite navigation business, freed my country from the dependence on foreign satellite navigation systems in terms of satellite applications, and broken the monopoly of the US GPS. With the development of the system, Beidou satellite navigation It is bound to be more and more widely used. At present, the transceiver channel of the frequency conversion module can only send and receive signals of a single frequency point. To receive multiple frequency points, the number of receiving channels must be increased. The expansion of multi-channel interfaces for communication equipment not only wastes hardware resources, but also incr...
