Abstract

The invention provides a radio frequency front-end amplification circuit, a chip, equipment and a configuration method. The radio frequency front-end amplification circuit comprises at least two low-noise amplification modules; each low-noise amplification module is used for amplifying one path of input voltage signal and converting the input voltage signal into one path or multiple paths of intermediate current signals; and the voltage output module is connected with each low-noise amplification module and is used for combining the intermediate current signals output by each low-noise amplification module and then converting the intermediate current signals into one or more paths of output voltage signals. The radio frequency front-end amplification circuit can be applied to a radio frequency front end with a multiple-input-multiple-output structure.

Description

technical field [0001] The present application belongs to the field of communication technology, and relates to a radio frequency front-end amplifier circuit, in particular to a radio frequency front-end amplifier circuit, a chip and a device suitable for multiple input and multiple output. Background technique [0002] At present, more and more RF front-ends are designed with a Multiple Inputs Multiple Outputs (Multiple Inputs Multiple Outputs, MIMO) structure. For example, today's set-top boxes are increasingly being designed with multiple tuners to simultaneously receive multiple channels from the same source. In addition, today's set-top boxes are also increasingly designed to have multiple RF inputs to receive signals from two or more sources, such as satellite set-top boxes, which are designed to receive two or more LNBs (Low Noise Block, Low Noise Down Converter), or receive signals in additional channels outside the traditional satellite intermediate frequency band ...
