Abstract
The invention relates to the field of a communication technology and discloses a radio frequency circuit and electronic equipment, aiming to solve the technical problem in the prior art that the radio frequency circuit has complicated wire arrangement. The radio frequency circuit comprises N communication modules, an address decoder and a configuration bus, wherein the address decoder is connected with the N communication modules; the configuration bus is connected with the address decoder; a first configuration parameter is sent to the address decoder after the configuration bus obtains the first configuration parameter, so that first address information is obtained, and the first communication module corresponding to the first address information is determined from the N communication modules; then the first configuration parameter is sent to the first communication module and is used for carrying out parameter setting on the first communication module by the first configuration parameter. Namely, the parameter setting of at least two communication modules can be realized by using only one configuration bus, so that the quantity of the configuration bus is reduced, and the technical effect of the wire arrangement complexity of the radio frequency circuit is achieved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency circuit and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic technology has also been developed rapidly, and more and more electronic devices have been produced, such as mobile phones, tablet computers, notebook computers and so on. These electronic devices have increasingly powerful functions and have become an indispensable part of people's lives. [0003] Many electronic devices have communication functions, and can receive or send data. In order to realize the communication function, these electronic devices are equipped with radio frequency circuits, such as figure 1 This is a schematic diagram of a radio frequency circuit, specifically including: [0004] A wireless local area network (WLAN: Wireless Local Area Networks) module 10a, used for data transmission through the wirel...
