Automatic microwave electronic adjustable loading device and detection method thereof

The invention relates to an automatic microwave electronic adjustable loading device, which is used for simulating a matching state of an antenna port of a to-be-detected piece so as to detect an antenna mismatching load alarm module of the to-be-detected piece. The device comprises a forward signal generator, a forward radio-frequency power amplifier, a reverse signal generator, a reverse radio-frequency power amplifier, a radio-frequency signal coupler, a power meter, a radio-frequency terminal load and a computer. The device judges the running state of the antenna mismatching load alarm module of the to-be-detected piece and the precision of the alarm module by simulating different standing-wave ratio outputs based on simulating a working condition of a base station of a specific to-be-detected piece. Through the device, the detection is more precise, the running is faster and the detection time is efficiently shortened, so the production efficiency is promoted and the manufacturing cost of a to-be-detecte
