The invention discloses a radio frequency (RF) front-end module, an integrated RF receiver chip, and a control method for the integrated RF receiver chip. The radio frequency (RF) front-end module comprises a low noise amplifier, a first resonance circuit, an auxiliary calibration oscillator, and an RF filter, wherein the low noise amplifier is electrically connected with both the first resonancecircuit and the RF filter; the first resonance circuit is electrically connected with the auxiliary calibration oscillator; the auxiliary calibration oscillator is used for controlling the first resonance circuit, so as to work at a frequency required by a user; and the first resonance circuit is used for enabling the low noise amplifier and the RF filter to work at the frequency required by the user when the auxiliary calibration oscillator is closed. The RF front-end module, the integrated RF receiver chip and the control method provided by the invention have the advantages that the low noise amplifier and the RF filter are integrated through the first resonance circuit and the auxiliary calibration oscillator, so that the integration level of the RF front-end module is improved, the size of the chip with the RF front-end module is reduced, and the production cost of the chip with the RF front-end module is lowered.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a radio frequency front-end module, an integrated radio frequency receiver chip and a control method. Background technique [0002] With the development of microelectronics technology, the integration and versatility of other modules are getting higher and higher. However, the integration and versatility of RF front-end modules have hardly improved for a long time. Specifically, the existing RF front-end module includes a low-noise amplifier, an off-chip RF filter, and an on-chip RF amplifier that are electrically connected in sequence. The externally received RF signal is amplified by the low-noise amplifier and then transmitted to the off-chip The RF filter performs filtering processing to suppress unwanted signals in the RF signal, and then transmits the processed RF signal to the on-chip RF amplifier for amplification processing. Therefore, due to the off-chip configura...
