9. A radio frequency conduction test apparatus, wherein the apparatus is in radio frequency conduction testing, and the apparatus comprises a radio frequency circuit, a first pad, and a second pad, wherein the radio frequency circuit comprises a radio frequency front-end circuit and a radio frequency back-end circuit, the first pad is connected to the radio frequency front-end circuit, the second pad is connected to the radio frequency back-end circuit, and the radio frequency front-end circuit and the radio frequency back-end circuit are in an off state; and the first pad and the second pad are pads for a serial device to be welded into the radio frequency circuit; and
during the radio frequency conduction test, the first pad is configured to transmit a test signal to a radio frequency test probe after the radio frequency test probe is moved to the first pad, wherein the test signal in the radio frequency test probe is transmitted to a radio frequency test instrument via an impedance conversion apparatus and a directional coupler, a straight-through output port of the directional coupler is connected to a first measurement port of the radio frequency test instrument, and a coupling output port of the directional coupler is connected to a second measurement port of the radio frequency test instrument.
