The application discloses a multi-mode radio frequency circuit, a radio frequency signal transmission method, device and electronic equipment, which belong to the field of radio frequency front ends. The multi-mode radio frequency circuit includes a transceiver, and a first signal path, a second signal path, and a third signal path electrically connected to the transceiver; when the multi-mode radio frequency circuit is in the first mode, the transceiver is electrically connected to the first signal path Connected, the transceiver transmits or receives the first signal through the first signal path; when the multi-mode radio frequency circuit is in the second mode, the transceiver is electrically connected with the second signal path, and the transceiver transmits or receives the first signal through the second signal path ; When the multi-mode radio frequency circuit is in the second mode, the transceiver is electrically connected to the third signal path, and the transceiver transmits or receives the second signal through the third signal path. The multi-mode radio frequency circuit can enable the first signal and / or the second signal in different modes to be transmitted on the same radio frequency architecture, which enhances the compatibility of the radio frequency architecture under the requirements of multiple modes.
Description
technical field [0001] The application belongs to the field of radio frequency front-end technology, and in particular relates to a multi-mode radio frequency circuit, a radio frequency signal transmission method, device and electronic equipment. Background technique [0002] With the continuous evolution of communication standards, the standards and frequency bands that terminals need to support continue to increase. For example, 5G mobile phone terminals need to support different frequency bands such as 2G / 3G / 4G / 5G. In addition, different countries and regions (Greater China, Europe, Australia, Southeast Asia, etc.) need to support different combinations of CA (Carrier Aggregation, carrier aggregation) and ENDC (EUTRA-NR Dual Connection, evolved base station and new air interface dual connection) Standards, which requires communication developers to design different radio frequency architectures to meet the requirements of different countries and regions for different stan...
