Abstract

The embodiment of the invention discloses a power detection circuit, a power amplifier module and a radio frequency front-end architecture. The power detection circuit comprises an envelope amplifier circuit and a plurality of current proportional amplification circuits, wherein the input ends of the plurality of current proportional amplification circuits are all connected with a radio frequency input signal RFin, the output ends of the plurality of current proportional amplification circuits are connected to the input end of the envelope amplifier circuit in parallel, and at least two current proportional amplification circuits are started in sequence along with the gradual increase of the radio frequency input signal RFin. Each current proportional amplification circuit amplifies the radio frequency input signal RFin after being started, and outputs a current amplification signal; and the envelope amplifier circuit is used for converting the current amplification signal into a voltage value and outputting the voltage value, so that a power detection function is realized, and the power detection function in a wide power range can be realized through the mode.

Description

technical field [0001] The invention relates to the technical field of power detection, in particular to a power detection circuit, a power amplifier module and a radio frequency front-end architecture. Background technique [0002] In the radio frequency system, the power detector is used to detect the power of different nodes, so as to adjust the gain or output power, etc. Therefore, the power detector has been widely used in the radio frequency system. A radio frequency (RF) power detector is used to measure the power of an RF signal to control the output power of an RF amplifier to ensure that the amplifier transmits the RF signal at the proper amplitude. In the process of power detection, it is usually expected that the RF power detector is only sensitive to the power delivered by the monitored RF signal source, and is insensitive to other RF signal sources, such as reflected signals and environmental noise, so as to avoid other RF signals. Source interference affects ...
