Abstract

The invention relates to the field of circuits. The invention provides an impedance-adjustable circuit, and the circuit comprises a first impedance tuner which comprises a first clock signal transmission line, a first data signal transmission line, and an impedance-variable device; in response to an acquired first clock signal of the first clock signal transmission line and an acquired first data signal of the first data signal transmission line, the first impedance tuner adjusts an impedance value of the impedance variable device to a first impedance value, the first impedance value is an impedance value corresponding to the first clock signal and the first data signal; the first impedance value is used for performing radio frequency debugging on the impedance adjustable circuit to obtain a radio frequency index. The clock signal of the first clock signal transmission line is modified, and a data signal of the first data signal transmission line selects a corresponding impedance value, so that the condition that an impedance element in the matching circuit is manually replaced to carry out radio frequency debugging is avoided; therefore, debugging time is saved, and efficiency is improved.

Description

technical field [0001] The present application relates to the field of circuits, in particular to an impedance adjustable circuit. Background technique [0002] As a part of the RF circuit, the matching circuit carries the bridge of input and output. In order to ensure the effective transmission of signals or energy from the "signal source" to the "load", it is necessary to use a matching circuit for impedance matching circuit debugging to achieve the best RF performance. excellent. [0003] With the rapid development of wireless communication nowadays, 5G applications are becoming more and more widely used. SUB6G and subsequent millimeter-wave UHF products have higher and higher requirements for RF circuits. The extremely small resistance-capacitance deviation is very important for the resistance-capacitance devices of UHF products. In other words, it will make the impedance value of the radio frequency circuit differ by orders of magnitude. Since the RC sensing parameter...
