March 31 News: According to information from the National Intellectual Property Administration, Shenzhen Guangheton Wireless Co., Ltd. has applied for a patent titled “Temperature Detection Circuit, RF Module, and Electronic Device.” The authorized publication number is CN224051463U, and the authorized publication date is March 27, 2026. The application number is CN202520794514.2. The application was published on March 27, 2026. The application date is April 24, 2025. Inventors include Xue Jing and Wen Dingning. The patent agent is Shenzhen Shiji Hengcheng Intellectual Property Agency Co., Ltd., and the patent agent is Zhang Yingya. Classification numbers are G01K7/22, G01K7/02, G01J5/00, H04B1/40.

The patent abstract shows that this application discloses a temperature detection circuit, RF module, and electronic device, relating to the field of temperature detection technology. The temperature detection circuit includes a first temperature detection device, a second temperature detection device, and a switch assembly. The first temperature detection device is arranged near one of multiple power amplifiers to detect the temperature of the power amplifier positioned adjacent to it. The second temperature detection device is arranged near another one of multiple power amplifiers to detect the temperature of the power amplifier positioned adjacent to it. A first terminal of the switch assembly is connected to an input terminal of a temperature controller, and two second terminals of the switch assembly are respectively connected to the first temperature detection device and the second temperature detection device. The switch assembly is configured to conduct an electrical connection between the first terminal and any one of the second terminals, and to disconnect the electrical connection between the first terminal and the remaining second terminals, outputting corresponding temperature detection signals to the temperature controller. This application aims to improve the accuracy of temperature detection for power amplifiers.
