Abstract

The invention discloses a radio frequency front-end circuit and electronic equipment. The radio frequency front-end circuit comprises a first signal receiving channel, a second signal receiving channel and a radio frequency transceiver, wherein the first signal receiving channel comprises an input module, an output module and a transmitting module; the input module receives medium-high frequency signals and outputs the medium-high frequency signals to the transmitting module; the transmitting module transmits the medium-high frequency signal to the radio frequency transceiver through the output module; the second signal receiving channel receives a low-frequency signal and outputs the low-frequency signal to the radio frequency transceiver; the structure of the transmitting module can be effectively simplified, so the effect of reducing the cost is achieved, and the problem of high cost in an existing radio frequency architecture is solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a radio frequency front-end circuit and electronic equipment. Background technique [0002] Since the 3GPP standard LTE release10 standard, it has supported carrier aggregation (hereinafter referred to as CA: CarrierAggregation, carrier aggregation). and downstream throughput. LTE CA is mainly divided into in-band continuous CA, in-band non-continuous CA and inter-band CA. Regardless of the form of CA, its outstanding advantage is to increase the channel bandwidth. [0003] There are three main factors affecting LTE throughput: channel bandwidth, MIMO form, and debugging method. For the two forms of LTE single-band and CA, there is no difference between the MIMO form and the modulation method. The biggest difference lies in the channel bandwidth. Generally, the maximum channel bandwidth of LTE is 20MHz. However, referring to the support capability of the current p...
