The invention discloses a high-performance broadband radio frequency receiving module. The high-performance broadband radio frequency receiving module comprises a radio frequency input port and a clock input port. the clock input port is connected with the input end of the two-way power divider; one output end of the two-way power divider is connected with one input end of the second mixer; the other output end of the two-way power divider is connected with one input end of the first mixer; The radio frequency input port is connected with the other input end of the first mixer, the output endof the first mixer is connected with the other input end of the second mixer, and the output end of the second mixer is connected with the intermediate frequency output port through a second intermediate frequency filter circuit, a second intermediate frequency amplification circuit, a second attenuator and a high dynamic amplifier which are sequentially connected. Only one radio frequency input port is arranged in the full frequency band; The radio frequency receiving module has the advantages of reduced size, reduced power consumption, module integration, miniaturization and low power consumption design, and the internal circuit of the module is simplified.
Description
technical field [0001] The invention relates to the technical field of radio frequency receiving modules, in particular to a high-performance broadband radio frequency receiving module. Background technique [0002] 30MHz ~ 8GHz high-performance reconnaissance equipment is widely used in national defense and civilian markets. However, the large size, heavy weight and high power consumption of the equipment seriously restrict its application, especially not suitable for portable applications. How to reduce device power consumption, reduce its size, and reduce its weight has always been the goal of relevant researchers. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a high-performance broadband radio frequency receiving module, which has wide instantaneous signal bandwidth, high rec...
