TranslateAir Tubular Trimmers
Air tubular trimmer capacitors are a type of precision variable capacitor that use air as the dielectric and a tubular mechanical structure to allow fine capacitance adjustment. They are commonly used in RF and microwave circuits where very low loss and high Q are required. Air is an excellent dielectric for RF components. Because of this, air trimmers achieve very high Q factors compared with most ceramic trimmers. Air tubular trimmers are commonly used in RF transmitters and receivers, LC resonant circuits, antenna matching networks, RF filters, test instruments, and microwave prototypes.
