Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a programmable control inductor. Background technique [0002] In 1831, Michael Faraday discovered the phenomenon of electromagnetic induction, which revealed the interconnection between electric and magnetic phenomena. Therefore, the phenomenon of electromagnetic induction has been widely used in electronic technology and electromagnetic measurement.

Problems solved by technology

[0003] Radio frequency components are necessary components of radio frequency (RF) circuits in the fields of mobile communication, wireless LAN (WLAN), television, network, etc. Current radio frequency components, such as radio frequency power amplifiers (Power Amplifier, PA), require impedance The matching network performs impedance matching with the downstream components, that is, the characteristic impedance of the impedance matching network is equal to that of the downstream components. The general matching method is to manually replace the inductance to adjust the inductance, so that the impedance matching network and the downstream components can achieve impedance matching. The manual adjustment method is not only cumbersome to operate, but also difficult to guarantee accuracy.
