Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a liquid metal variable capacitor. Background technique [0002] A variable capacitor is a capacitor whose capacitance can be adjusted within a certain range. It is an important component in variable frequency oscillators, adjustable amplifiers, phase shifters, and impedance matching circuits. Parameters such as capacity density and adjustment range of a variable capacitor directly determine its application range. Therefore, designing a variable capacitor with small volume, large capacity, and large adjustment range is a long-term problem to be solved in this field. [0003] Variable capacitors in the prior art include two types: air-dielectric variable capacitors and air-film variable capacitors. The air dielectric variable capacitor is a typical traditional variable capacitor, which changes the capacitance value by changing the relative effective area between two el...
