Description

technical field [0001] The present application relates to the technical field of radio frequency communication, in particular to a debugging method, device, computer equipment and storage medium of electronic product debugging equipment. Background technique [0002] Impedance matching is mainly used on transmission lines to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, thereby improving energy efficiency. The internal resistance of the signal source is equal to and in phase with the characteristic impedance of the connected transmission line, or the characteristic impedance of the transmission line is equal in magnitude and in phase with the connected load impedance, which means that the input or output of the transmission line is in impedance matching state. Taking a Bluetooth headset as an example, the Bluetooth headset includes a headset CPU (Central Processing Unit, central processing unit) chip, a Bluetooth antenna,...

AI Technical Summary

Problems solved by technology

However, this is limited to theoretical calculations. In practice, when debugging impedance matching, the port impedance of the network analyzer is the standard 50 ohms

The impedance value and resonant frequency measured at the antenna end after passing through the matching circuit are calculated with reference to 50 ohms. If the impedance of the chip end is not equal to 50 ohms, impedance matching cannot be achieved, and the signal will not be able to achieve maximum power transmission, that is The traditional impedance matching method has the problem of low impedance matching accuracy
