Description

technical field [0001] The invention belongs to the technical field of millimeter waves, in particular to a 18-30GHz front-end receiving component. Background technique [0002] With the rapid development of millimeter wave communication, radar and electronic countermeasures and other fields, the processing requirements for millimeter wave radio frequency signals are getting higher and higher, especially the demand for large dynamic range and highly integrated millimeter wave logarithmic video detection components increasing day by day. [0003] For low-frequency radio-frequency microwave signals, the usual method is to use a suitable detection device to directly convert the radio-frequency signal into a video signal for digital signal processing. However, for millimeter wave, due to its high frequency, detection devices directly applicable to millimeter wave signals are extremely scarce, resulting in a serious shortage of millimeter wave detection components that can meet ...
