Chip testing device

The invention relates to a chip testing device, which comprises a testing base, a radio frequency microwave detection body is embedded in the testing base, the radio frequency microwave detection bodycomprises a conductor, a radio frequency elastic probe externally wrapped by an insulating sleeve is inserted into the upper portion in the conductor, and a plurality of auxiliary grounding elastic probes are arranged on the outer side of the radio frequency elastic probe in the circumferential direction in a surrounding mode. The upper end part of the radio frequency elastic probe is in contactwith a radio frequency microwave signal port of a tested object, the lower end part of the radio frequency elastic probe is conductively connected with a radio frequency inner conductor arranged at the middle part in the conductor, a radio frequency cable is inserted into the lower part in the conductor, and a central conductor in the radio frequency cable is conductively connected with the lowerend part of the radio frequ
