The invention provides a radio frequency modulation signal processing method and device and a receiver. The method comprises the steps of amplifying received radio frequency modulation signals through a first low noise amplifier; carrying out power distribution on the amplified radio frequency modulation signals through a preset groups of second low noise amplifiers and radiation frequency switches corresponding to signal channels and / or a system; carrying out correlation on the radio frequency modulation signals after the power distribution, through the signal channels and / or a radio frequency correlation circuit of the system, wherein the second low noise amplifiers and the radio frequency switches are integrated into a radio frequency chip. According to the embodiment of the invention, through arrangement of the preset groups of second low noise amplifiers and the radio frequency switches which are integrated into the radio frequency chip and correspond to the signal channels and / or the system, on the premise of ensuring the isolation degree, power distribution of the multi-way signal channels and / or the system is realized, a size of a circuit is reduced, and the integration degree of the circuit is improved.
Description
technical field [0001] This article involves but is not limited to radio frequency communication technology, especially a method, device and receiver for realizing radio frequency modulation signal processing. Background technique [0002] In the radio frequency receiver, the low noise amplifier and the power splitter are the two main components for processing the received radio frequency modulation signal; Among them, the low noise amplifier (LNA) is the first stage gain stage circuit of the radio receiver, it must Meet multiple performance requirements at the same time, mainly including: 1. The RF signal received by the antenna is generally very weak, and the subsequent stage circuit of the LNA (such as a mixer) cannot achieve high gain and low noise, so the LNA must meet a certain gain Requirements; 2. In order to improve the reliability of signal demodulation, the received signal needs to have a certain signal-to-noise ratio (SNR), which requires the noise introduced by ...
