Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency device testing, in particular to a high temperature testing device for radio frequency devices. Background Art

[0002] Common RF devices mainly include power amplifiers, duplexers, RF switches, filters, low noise amplifiers, etc. Filters are widely used in the communication field as a frequency selection device. When in use, external signals are transmitted to the inside of the filter through the connector on the filter to filter out clutter or interference signals. During the manufacturing process of the filter, it is necessary to perform high temperature detection on it to test the life of the filter under high temperature conditions.

[0003] Chinese patent authorization announcement number CN216646685U discloses a special test equipment for high-temperature life test of filters, including a high-temperature test box, a threaded connecting rod is fixedly installed on one side of the bottom of the high-temperature test box, the bottom end of the threaded connecting rod is threadedly connected with an anti-drift device, installation grooves are opened on both sides of the top of the high-temperature test box, bearings are embedded and installed on both sides of the inside of the installation groove, and a portable device is connected to the inside of the installation groove through the bearing, a hinge is detachably installed on one side of the front of the high-temperature test box, a box door is detachably installed on one side of the hinge, and a door handle is fixedly installed on one side of the front of the box door. In the above scheme, the test equipment uses the anti-drift device to stabilize the high-temperature test box, so that there is no safety hazard in the device, and avoids the problem that because the test equipment itself does not have an anti-drift function, once the test equipment is slightly hit, it will cause the equipment to move, thereby causing a safety hazard to the device. The above-mentioned existing technical solution has the following shortcomings: this technical solution reduces losses by using portable equipment to transfer the high-temperature test box and avoids the problem that the test equipment itself does not have an anti-falling function. However, this technical solution still has room for optimization in the processing after the high-temperature test, and it is difficult to cool the device. We need to make further improvements in this regard. Utility Model Content
