WR340 Waveguide Specifications
WR340 waveguides are transmission line structures for guiding electromagnetic waves. Other components assist in various processes, depending on the function of the device itself. Certain components may assist with coupling, sampling, transmitting, combining, circulating, dividing, mixing, and/or terminating signals at a specified frequency.
In high-power microwave and RF engineering, WR340 is a classification and size of waveguide. The ‘WR’ is shorthand for ‘Waveguide, Rectangular.’ The ‘340’ is indicative of the inner width of the waveguide, in hundredths of an inch. Thus, a WR340 component has an inner dimension of 3.40 inches (86.36 mm), and is made of rectangular waveguide.
Other details, technical information, and general specifications for WR340 waveguide are as follows:
| EIA Standard | IEC Standard | Frequency Range | Frequency Band | Inner Dimensions (mm) |
| WR340 Waveguide | R26 Waveguide | 2.20 to 3.30 GHz | S-Band | 3.40 in. x 1.70 in. (86.36 mm x 43.18 mm) |
A common center frequency for WR340 waveguide components is 2450 MHz.
