Waveguide Shorts/Shorting Plates

Waveguide shorts, or shorting plates, are components used to reflect microwave signals within a waveguide system, effectively terminating the waveguide in its characteristic impedance. They are crucial for testing, measurements, and system calibration, providing a precise method for creating a known reflection point in microwave and RF applications.

Dolph Microwave excels in the design and manufacture of high-quality waveguide shorts and shorting plates, crucial for creating high-reflection short circuits in waveguide systems. These components are essential for precise signal termination, ensuring optimal performance across a wide range of microwave and RF applications. With compatibility from WR2300 to WR10, our waveguide shorts are suitable for all standard waveguides, offering versatility and reliability for engineers and technicians alike.
