The invention discloses a manufacturing method of a push-type mineral-insulated radio frequency cable and the radio frequency cable. The method comprises the following steps: mixing silicon dioxide or aluminum oxide powder with an assistant; manufacturing the mixture into a hollow insulating rod through a rod press; putting the insulating rods into push equipment and then sequentially sleeving a mold core with the insulating rod and a mold sleeve to form an insulating core wire through pushing the insulating rod; heating and solidifying the pushed insulating core wire in an oven; penetrating the solidified insulating core wire into a stainless steel shielding tube; and carrying out tube drawing and annealing. Through the radio frequency cable obtained by the manufacturing method, the manufactured insulating medium is relatively uniform; the reflection loss of the signal in the transmission process is reduced; standing waves and attenuation of the cable are reduced; the electrical property of the cable is relatively good; the targets of large-length production and length adjustment of an insulator by adjusting the size of the insulating rod can be achieved through a push technology; and by the push technology, the cable does not need to be repeatedly drawn at the later manufacturing period, so that the problem that an inner conductor is broken off is solved.
