Abstract
The present invention relates to a radio frequency circuit structure for implementing a function of converting a satellite signal of a global navigation satellite system into a baseband signal. The radio frequency circuit structure comprises a channel dividing function module, a plurality of frequency converting function modules, a plurality of local oscillator signal modules, and a plurality of analog-to-digital convertor modules. The channel dividing function module is used for dividing a satellite signal of the global navigation satellite system received by an antenna into satellite signals in a plurality of channels. Each of the frequency converting function modules is used for performing frequency conversion on the satellite signals in the corresponding channels to form near zero-frequency signals. Each of the local oscillator signal module is used for generating a local oscillator signal and outputting the local oscillator signal to the frequency converting function module. By using the radio frequency circuit structure for implementing a function of converting a satellite signal of a global navigation satellite system into a baseband signal, frequency conversion and follow-u…
