Microwave PIN type switch broadband feed structure applied to millimeter wave security inspection equipment

The utility model discloses a microwave PIN type switch broadband feed structure applied to millimeter wave security inspection equipment, and belongs to the technical field of microwaves. The problems that in the prior art, a chip capacitor and a gold wire capacitor of an existing feed structure need to be purchased, the chip capacitor and the gold wire capacitor need to be manually assembled in a circuit during assembly, the production efficiency is reduced while the cost is increased, and due to manual operation, the positions of the capacitors and the lengths of gold wires are different, and the batch consistency is poor are solved. According to the technical scheme, the microwave filter comprises a microwave substrate, a first micro-band inductor is arranged on the microwave substrate, one end of the first micro-band inductor is connected with a microwave transmission line, the microwave transmission line is connected with a microwave circuit, the first micro-band inductor is further connected with a sec
