Abstract

The invention discloses a radio frequency front-end device slave control interface device which is based on an MIPI RFFE v2.0 protocol and can be integrated on the whole chip. The radio frequency front-end device slave control interface device in the invention is built by adopting a digital logic unit and a basic circuit element, so that in-chip integration of a slave controller circuit can be easily realized; the slave controller can be integrated into a radio frequency front-end element piece; and only through three signal lines of VIO, SCLK and SDAT of an MIPI RFFE interface, flexible control of the radio frequency front-end element can be realized. The number of the output pins of the processor is small, so that the area of the printed circuit board occupied by the control signals is small; extra board-level components do not need to be used, so that the cost required by implementing the radio frequency front-end device slave control interface device is low, the occupied equipmentspace is small, and miniaturization and low-cost design of the mobile equipment are facilitated; and the radio frequency front-end device slave control interface device is extremely suitable for control of various radio frequency front-end devices in the mobile industry.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to the design of a slave control interface device of a radio frequency front-end device. Background technique [0002] With the rapid development of mobile communication technology, modern mobile products such as mobile phones, mobile computers and other equipment are developing towards lighter and thinner. In addition to RF transceivers, RF front-end devices such as power amplifiers, low-noise amplifiers, filters, switches, power management modules, and antenna tuners are also widely used in these modern mobile communication devices. Most of these RF front-end devices are controlled and configured by the master controller through the digital bus. [0003] In order to unify industry norms, many standardization organizations have formulated communication standards suitable for mobile devices. Among them, the most eye-catching and the most widely used is the...
