E-Plane Miter Bend
Look for WTEB in the model code. The published E-plane rows list Full BW. Match the A×B size to the planned bend in your drawing.
The sketch illustrates the bend type, not flange geometry or part dimensions.
Waveguide Miter Bends
Waveguide miter bends are precision-engineered components used to change the direction of microwave signals within a waveguide system. They are designed for minimal signal loss and reflection, ensuring efficient signal transmission. These bends are critical in complex microwave systems, radar, satellite communications, and testing setups, accommodating various angles to meet specific design requirements.

Waveguide Miter Bends E-Plane & H-Plane
Need a waveguide run to turn a corner? Start with your WR size and the direction of the bend. The model table gives you the flange options, standard A×B dimensions and RF figures for each version.
- 90° bends are standard; ask about 30°, 45° or 60°.
- 6061 aluminum is the stated standard body material; copper and brass are described as options.
- Custom flange types, dimensions and E/H combinations can be reviewed against a drawing.

Already have a part number?
Check it in the full model table below. Keep the E/H suffix when you enquire.
Replacing an installed bend?
Send a photo or drawing of both flange faces and the available space around the corner.
Need a different route?
Include the bend angle, A×B dimensions and any flange or finish changes.
Bend orientation
Choose the bend that turns in the right plane.
E-plane and H-plane models can have the same WR size and frequency range, but their published bandwidth and standard leg dimensions differ.
H-Plane Miter Bend
Look for WTHB in the model table. These rows list 20% operating bandwidth. Their standard A×B dimensions often differ from the E-plane version.
The sketch illustrates the bend type, not flange geometry or part dimensions.
Unsure which one matches your run? Share a photo or drawing showing the waveguide’s broad face and the direction of the turn. For another routing option, see waveguide twists when the orientation must rotate rather than the path simply turning.
Mechanical fit
Check the space around the corner before ordering.
Two bends with the same WR size can take up different amounts of space. Use the A×B entry in the exact E-plane or H-plane row, then check both ends against the equipment you are joining.
- A × B: use the two leg dimensions printed for the selected model, in millimetres.
- Flange 1 and flange 2: specify each mating flange and its orientation.
- Installation space: note nearby hardware, covers or supports that limit the bend.
- Replacement parts: an existing drawing or a clearly labelled photo helps confirm the geometry.
The older manufacturer’s PDF also labels Flange 1, Flange 2, A and B, but some of its dimensions differ from the current online table. Open the original miter-bend PDF.
Flange interfaces
The flange needs to match at both ends.
The model table lists a cover and a grooved flange designation for every row. Do not pick a flange only because its waveguide size looks right: the aperture, bolt pattern and sealing face need to match the equipment on each side.
- For a cover/flat end, use the exact designation from the selected row.
- For a grooved end, check the matching face and any required gasket or seal.
- If the two ends are different, state both end interfaces in your drawing or enquiry.
Standard material
6061 aluminum is stated in the product features. Copper and brass are also described as options.
Model-table material
Each published row lists Al/Cu. State the required body material in the enquiry.
Finish to confirm
Chromate/Painted is listed in the table. The page separately mentions grey paint and flat black; confirm the selected finish.

Check the right revision.The archived PDF lists a narrower range and some different A×B sizes. Use the current model row as a starting point and request the selected model’s latest drawing before manufacture.
PDF and STEP labels.The original table shows PDF and STEP for each model. Individual file addresses are not exposed by the source, so these labels are retained without pretending they are downloadable files. Request the files for your part number. The WR187 rows also print “PDR348” as the grooved flange code; confirm this designation against the latest drawing before ordering.
Published electrical data
Use the RF figures from your own model row.
The page also contains a general VSWR statement and an older specification example. Those are not substitutes for the model-by-model figures.
1.15:1 for the DH-3 and DH-4 E/H models; 1.1:1 for the remaining published rows.
0.15 dB, 0.2 dB or 0.25 dB, depending on the selected model. Check its exact value above.
It states VSWR “typically better than 1.05” and “as low as 1.03:1 over a 5% bandwidth.” It does not assign these values to all models.
Original “Product Specifications Example”
The manufacturer also publishes this example. It is reproduced here for completeness, but its frequency range conflicts with the DH-100 rows in the current catalog.
| Type | DH-100 WTEB |
|---|---|
| Frequency Range | 0.32 to 3.3 GHz |
| Max VSWR | 1.1:1 |
| Operating Bandwidth | 20% |
| Waveguide Sizes | WR-340 to WR-2300 |
| Material | Aluminum, Copper |
| Finishes | Chromate inside, Grey paint outside |
| Flange Type | UG, CPR, Custom |
Important: the current DH-100WTEB row states 8.20–12.40 GHz, and DH-100WTHB states 8.20–12.4 GHz. Please check the model-specific datasheet before using the older example in a design.
Ordering code
Have the model number? Keep the full code.
This is the manufacturer’s published ordering example. It identifies the WR size, bend type, A×B dimensions, flange configuration and material.
DH-100WTEB25*25PMA
If a part is being replaced, send the existing full code and a photo or drawing of the flange ends. A WR number alone does not identify the complete bend.
Check the quote detailsDolph Microwave prefix in the example.
Waveguide Size | WR90
Waveguide Type | Miter E-Bend Waveguide
Waveguide Type | Miter H-Bend Waveguide, as printed in the original part-number guide.
A*B Length | 25*25 mm
Flange Type | Rectangular Flat
Flange Type | Rectangular Grooved
Material | Aluminium, Cu
Code check: the ordering guide says “WHB” for H-bend, but the H-plane entries in the current model table use “WTHB.” State the full model and confirm the H-plane code before ordering.
Where these bends are used
For fixed turns in a rectangular waveguide run.
Use the bend plane and the actual installation drawing to select the part, rather than choosing from an application name alone.
- Radar systems: waveguide routing inside radar equipment.
- Satellite communications: routing in ground-station RF paths.
- Telecommunications: directional changes in microwave infrastructure.
- Research and testing: arranging waveguide paths in lab and test systems.
- Aerospace: routing in communication or navigation assemblies.
Build options and surface finish
Put the material and finish on the drawing.
The product features specify 6061 aluminum for standard use, with copper and brass options. The model matrix gives Al/Cu and Chromate/Painted for every entry.
The page mentions chromate conversion inside and grey corrosion-resistant paint outside. Its additional note separately states SurTec/corrosion-protection treatment, flat-black paint and unplated, polished, SurTec-treated flanges. Other finishes and colors are described as available on request.
Grey and flat black are both mentioned in the original copy. State the required internal treatment, outer color and flange finish in your order documentation instead of assuming one universal finish.
Preformed bends and hybrid flexible waveguide assemblies are also mentioned as available. See flexible waveguide options or send your installation sketch for a non-standard assembly review.
Questions before you order
Clear up the details that change the quote.
Can I order a 45° bend?
The product describes 90° as standard and lists 30°, 45° and 60° as special-order angles. Include the desired angle and leg dimensions with your drawing.
Can I use the E-plane row for an H-plane bend?
No. Both types have their own rows. The source lists Full BW for E-plane entries and 20% for H-plane entries, with different A×B sizes in many cases.
Are both flanges the same?
Not necessarily. Tell the manufacturer the flange required on each end, with the mating part or flange drawing where possible. Use the specific cover/grooved designation in the chosen row as your reference.
Can I download a STEP file for my exact model?
PDF and STEP are shown for every row on the source page, but the public model-table file URLs could not be verified. Ask for the exact part number’s current STEP file and PDF drawing.
Does the page give a power rating?
The published miter-bend model table does not list a per-model power rating. Provide average/peak power and operating conditions if this matters for your system, and request confirmation for the selected build.
What if the catalog dimensions do not fit?
Send the usable space, required angle, WR size, both flange types and a sketch. The manufacturer describes special sizes, flange options and E/H combinations for review.
