Abstract

The invention relates to a radio frequency front-end transmitting circuit, a radio frequency front-end circuit, a transceiver and base station equipment. The aforementioned RF front-end transmitting circuit includes a pre-amplification unit, a combining unit and a broadband power amplifier unit. The pre-amplification unit is used for pre-amplifying the RF signal output by the RF transceiver module. The radio frequency signal includes a first radio frequency signal and a second radio frequency signal in different frequency bands. The combining unit is used for combining the first radio frequency signal and the second radio frequency signal respectively output by the pre-amplification unit, and then outputting a corresponding broadband radio frequency signal. The broadband power amplifier unit is used to amplify and process the broadband radio frequency signal and output it to the antenna. The new RF front-end transmitting circuit built by the pre-amplification unit, the combination unit and the broadband power amplifier unit replaces the traditional design scheme of using one power amplifier for one frequency band, and can reduce the required RF for the RF front-end processing of multi-band RF signals. The number of front-end transmitting circuits achieves the effect of greatly reducing costs.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a radio frequency front-end transmitting circuit, a radio frequency front-end circuit, a transceiver and base station equipment. Background technique [0002] With the development of mobile communication technology, the public's demand for instant data has doubled, and the fifth generation of mobile network technology - 5G has emerged, which can well meet this increasing demand for instant data. The arrival of 5G technology makes the data transmission rate faster, enables the interconnection of everything between base stations, cars, household appliances and other types of equipment, making cities more intelligent. Although 5G technology has many advantages, there are still many technical difficulties in 5G technology, and 5G base stations, networks, etc. need to be re-arranged, and it cannot completely replace 4G for a period of time. If there is a communicatio...
