Coaxial Stub Tuners: Capabilities and Design Overview
Microwave Techniques offers advanced designs for high-power RF components and passive microwave devices. As our capabilities continue to expand each year, so too does our trusted reupation for having quality components that exhibit superior performance. Specific to coaxial stub tuners, our capabilites and design overview includes:
- Double and triple stub configurations
- Frequencies from 915 MHz to 18.0 GHz
- Standard material options include copper and brass
- Standard design uses knurled clamps to set short positions
- Standard part finish is black paint, with other options available
Each stub is set to a variable height. It is connected at a right angle to the main coax transmission line. The position of each stub determines the potential for impedance matching and ease the facilitation of tuning.
