Guanghetong has obtained patents related to power amplifier devices, featuring an integrated switch to achieve signal transmission and reception, reducing circuit board layout costs.

March 31 News: According to information from the National Intellectual Property Administration, Shenzhen Goodix Tong Wireless Co., Ltd. has applied for a patent titled “Power Amplification Device, RF Front-End Equipment, and Mobile Terminal.” The authorized announcement number is CN224054231U, with the authorized announcement date of March 27, 2026. The application number is CN202520576537.6. The application publication date is March 27, 2026; the application date is March 27, 2025. Inventors are Liu Yijiang, Xu Shaofeng, and Xu Ning. The patent agency is Shenzhen Shiji Hengcheng Intellectual Property Agency Co., Ltd. The patent agent is Zhang Yingya. Classification numbers are H03F3/20, H04B1/40, H04B1/44, H03F3/68, H03F3/189, H03F3/181, H03F1/08.

The patent abstract shows that this utility model discloses a power amplification device, RF front-end equipment, and a mobile terminal, relating to the communications field. The power amplification device includes an intermediate-frequency power amplification module. The intermediate-frequency power amplification module has a receive/transmit mode switching switch built in. The receive/transmit mode switching switch includes a mode switching contact, a transmit contact, and a receive contact. When the mode switching contact is connected to the transmit contact, the intermediate-frequency power amplification module is in a signal transmit mode. When the mode switching contact is connected to the receive contact, the intermediate-frequency power amplification module is in a signal receive mode. Thus, by means of the built-in receive/transmit mode switching switch, the switching between receive and transmit can be implemented inside the intermediate-frequency power amplification module, without an external switching switch. Therefore, signal receiving/transmitting switching can be achieved, and there is no need to separately lay out an external switch on the circuit board, reducing the circuit board layout cost. It solves the technical problem of high circuit board layout cost.
