Before you order

Specify the installed shape, not only the length

Routing and support

Show the fixed points and flange faces on a simple sketch. This helps distinguish a routing adjustment from repeated movement during operation.

Loss and average power

The WR650 row lists 0.12 dB/m and 20 kW average power. The WR22 row lists 2.7 dB/m and 0.05 kW. Use the row for your operating band.

Core, jacket and temperature

The table lists Brass / BeCu cores with silicone jackets. The construction description also offers neoprene and states −20°C to +100°C; confirm the jacket for your order.

The flexible waveguide selection guide covers routing and bend requirements. For the installed run, compare waveguide supports and hangers.

Twistable and Seamless Flexible Waveguide
Twistable and Seamless Flexible Waveguide · Separate product option

For the rest of your setup

Do the flange faces also need to twist?

Bending in the E-plane or H-plane does not establish a torsion rating. If the ends need rotation relative to each other, compare the twistable range and specify the angle.

Before you order

What needs to match at the joint?

Aperture and height

Confirm the internal opening and whether the waveguide is full-height or reduced-height. The standard size name alone does not cover every custom interface.

Bolt pattern and mating face

Include the hole positions, flange outline and cover/grooved face. A clear drawing avoids relying on a partial flange name.

Material and seal

The source describes Aluminum 6061-T6 and custom groove options. State whether the assembly also needs a gasket, alignment pins or other mating hardware.

The EIA and IEC flange size guide explains designation and fit checks. For a thin interface component, compare waveguide flange shims.

For the rest of your setup

Specify the gasket with the flange

If the joint requires a seal, choose the gasket material and profile around the actual mating face. Pressure-only sealing and combined RF/pressure sealing call for different choices.

Questions before ordering

Will any two WR75 flanges connect?

The WR designation describes the waveguide size. The mating flange code, bolt pattern, aperture height and face geometry still need to agree.

Can you quote a non-standard flange?

Send a dimensioned drawing with the material, surface finish, mating part and operating conditions. The custom interface can then be reviewed as a specific part.

PRESSURE SEAL; or PRESSURE and RF SEAL ?
@If a Pressure seal only, then use a NON-CONDUCTIVE Gasket.
These are usually Silicon or Neoprene material, O-rings or Rectangles, designed to fit into flange grooves.
@If a Pressure and RF seal is required, then use a CONDUCTIVE Gasket.
These look similar to the non-conductive gaskets, but are filled with a conductive material, usually copper or silver. The exception is the Die-cut Gasket, which resembles the flange face.

Questions before ordering

Can you quote from an existing gasket?

Send its dimensions or a drawing, material if known, thickness and clear photographs of the flange face. Include pressure and temperature conditions.

Does the same WR size guarantee the same gasket fit?

No. The flange face, holes, grooves and seal profile also need to match. Supply the full flange designation or drawing.

Before you order

Start with power, then check the space

CW power comes first

The WR650 row lists 2–50 W, while the WR28 row lists 2–15 W. These are low-power loads; choose the exact rating to match the applied signal.

Overall length changes by band

The listed WR650 load is 160 mm long. The WR28 version is 20 mm long. The table retains the dimensions for every model between them.

Flange and finish

The table lists Al/Cu bodies with Chromate/Painted finish and IP65. Confirm the required cover or grooved flange and contact finish with the part number.

For a measurement setup, you may also need a waveguide fixed attenuator or a waveguide calibration kit.

Testing at more power?

A small termination is not a substitute for a higher-power load. If your test level exceeds the selected CW rating, compare the high-power termination range before placing the order.

Questions before ordering

Can this load be connected directly to a high-power amplifier?

Only if the power reaching the load is within its selected rating. The product table specifies low-power CW ranges, not unrestricted amplifier output.

What does “short” refer to?

It refers to the compact physical format of this matched load. It is not a waveguide shorting plate.

Before you order

Three choices decide the adapter

Where the cable exits

WHPCA identifies a right-angle adapter. WHPECA identifies an end-launch adapter. Check cable clearance and the direction of the waveguide run.

Connector type and gender

The part-number guide includes N, TNC, SMA and 2.92 mm codes, with K for female and J for male. The connector available depends on the selected model.

Power at the operating band

Lower-band rows list up to 1,500 W average power. The WR10 rows list 50 W, 1.4:1 VSWR and 1 dB insertion loss. Do not use one family-wide rating for every adapter.

For bench measurements, compare the waveguide calibration kits. Check the flange size and gasket-fit guide if the mating flange code is uncertain.

Coaxial Cable Connectors

For the rest of your setup

Check the cable end at the same time

An adapter order needs both the waveguide flange and the mating coaxial interface. Include the cable connector type and gender so the two sides can be checked together.

The main inputs are the finished barrier thickness, cutout and mounting pattern, pressure medium and differential pressure, gasket requirement, exact mating flange designations, and the dimensional or RF checks you need reported.

Barrier
Thickness, cutout, mounting holes, access and backing structure
Seal
Pressure medium, differential pressure, temperature and leakage limit
Flanges
Exact designation, aperture, bolt pattern, groove and orientation
Verification
RF test, dimensions, pressure or leak-test acceptance criteria as required

Bulkhead Feedthrough Selection Guide

Need the Waveguide Line Itself to Hold a Pressure Boundary?

A bulkhead feedthru mounts the waveguide through a wall or panel. If your requirement is a sealed RF window inside the waveguide path, review the Waveguide Pressure Windows family instead.

For replacement or project-specific sealing parts, see Waveguide Gasket, Die Cut.

Different Waveguide Family or Routing Requirement?

For broadband double-ridged interfaces, use the separate Double-Ridged Waveguide Bulkhead Feedthroughs range. If adjoining routing needs a flexible section, review Seamless Flexible WG.

For complete WR flange codes and standard references, use Waveguide Flange Standard EIA & IEC.
