Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0015] see figure 1 , the present invention provides a technical solution: in the first step, the signal is sent to the radio frequency (RF) input port of the mixer after being sampled, filtered and attenuated;
[0016] In the second step, the system sets the corresponding local oscillator signal (LO) according to different carrier frequencies and sends it to the LO input port of the mixer device;
[0017] In the third step, the mixed frequency signal is sent...
