Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular to a liquid crystal-based microwave and millimeter wave adjustable capacitor. Background technique [0002] Capacitance can be adjusted in a small range, and the capacitor that can be fixed at a certain capacitance value after adjustment is called an adjustable capacitor, also called a semi-fine-tuning capacitor, and the adjustable capacitor has no polarity. [0003] Traditional adjustable capacitors can be divided into mechanical adjustment and electrical adjustment. Among them, the adjustable capacitor of the electrical adjustment is referred to as the electrical adjustable capacitor, which plays an important role in the radio frequency circuit. [0004] Traditional electrically adjustable capacitors can be classified into varactor diode type variable capacitors, micro-electro-mechanical system (Micro-Electro-Mechanical System, MEMS for short) variabl...
