We can design and build them to suit your requirements just let us know what you need….
These switched inductors are formed from 0.5 inch diameter copper tubing which is supported on 1 inch ceramic insulators. Switches can be provided with up to 10 taps and if used with a 250pf tuning capacitor it is possible to cover from 3.3MHz to >30MHz (upper frequency limit depends upon stray circuit capacitances) at RF power levels in excess of 10kW.
The built in detent mechanism is designed to operate with standard 30 degree switches allowing other circuits, such as input matching networks to be selected by operating the main switch. The main spindle is designed to accept 0.25 inch coupling spindles which allows the user to incorporate insulated or metal hardware and to determine the optimum position for the inductor without having to worry about intermediate couplings etc.
A silver plated option is available and multiple wafers can be added if necessary.
Overall switch dimensions are (approximately) 7 x7 x 11.5 inches for the switched inductor shown in the photograph.
