WR284 Waveguide Vacuum Window
The WR284 Waveguide Vacuum Window from Dolph Microwave is designed to transmit RF or microwave power from a vacuum into an air or inert gas-filled transmission line with minimal loss. This resonant cavity maximizes power transmission over a specific frequency range and is commonly used in electron beam devices and RF systems using microwave energy.
