Abstract

The invention relates to the technical field of power amplifier detection, in particular to a power detection circuit and method of a power amplifier. When the power supply of the voltage bias circuit is powered on, the capacitor C1 provides conduction voltage drop for the MOS tube in the bias circuit, so that the voltage bias circuit gets rid of a zero-current state, and after the voltage bias circuit is started, the capacitor C1 is in a turn-off state, and at the moment, the starting circuit does not generate power consumption, namely no power consumption is generated, so that electric energy is saved; the direct current offset circuit and the offset compensation circuit are added on the basis of an existing power detection circuit, range adjustment of output current can be achieved, the compensation requirements of different amplifiers can be met, and flexibility is high.

Description

technical field [0001] The invention relates to the technical field of power amplifier detection, in particular to a power detection circuit and method of a power amplifier. Background technique [0002] Modern communication systems use more and more complex modulation methods, which makes the requirements for the linearity performance of RF power amplifiers higher and higher. In order to ensure the efficiency of the PA and improve the linearity performance of the power amplifier is a problem to be solved. [0003] Since the compensation requirements of different amplifiers will change according to the input power, the traditional power detection circuit has a relatively single compensation function for different amplifiers and is less flexible. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a power detection circuit and method of a power amplifier, which aims to solve the technical problem that the compensation function of the power d...
