Catalog Model
Give us the product family, operating band, WR size, flange and quantity. If you already picked a model, send the PDF or STEP link.
Standard and custom waveguide — we make them in Xi’an
Waveguide Components Sales
Source individual components, matched interfaces or custom assemblies from one factory. We review your frequency band, WR size, flange, connector, power, pressure, routing, finish and test requirements before we quote.
- Published product families Standard and double-ridged models with specs and STEP files available.
- Drawing-based custom work Give us a PDF, STEP file, sketch, mating-part data or existing part number.
- Verification requirements Tell us what measurements, inspections and test records you need.

Pick the component type you need
Use the linked family pages for catalog models. If you need several functions built as one assembly, send us the complete RF path and we’ll review it together.
Straights and Bends
Fixed lengths, E-plane bends, H-plane bends, miter bends and routed sections.
Adapters and Transitions
Waveguide-to-coax, size changes, rectangular-to-circular and special interfaces.
Flexible and Flex-Rigid
Alignment sections, vibration accommodation and preformed flexible routing.
Couplers and Probes
Forward or reflected sampling, probe coupling and near-field measurement hardware.
Pressure Components
Pressure windows, inlets, bulkhead feedthroughs, seals and mating hardware.
Loads and Attenuators
Low-power and high-power terminations, fixed attenuation and water-cooled loads.
Rotation and Switching
Rotary joints plus manual or motorized switching for moving RF paths.
Calibration and Hardware
TRL kits, shorts, shims, gaskets, flange references, supports and dust covers.
Four ways to order
Buy a catalog part or get a custom interface
How we quote depends on how much of your RF path is already fixed. Send what you have — we can fill in the missing info before pricing.
Modified Interfaces
Keep the electrics and change the flange, connector orientation, length, finish, mounting points or installation envelope.
Replacement Part
Send us the old part number, drawing, measured dimensions and mating interfaces. Tell us if anything needs to change from the original.
Integrated Assembly
Combine bends, straights, transitions, flex sections, couplers or flanges into one tested RF path from a system drawing or sketch.
Standard product ranges
Compare by interface, frequency band and physical size
The numbers below describe family ranges, not a single universal spec. Final frequency, flange, power and environment specs are confirmed per model — not assumed across the whole family.
Waveguide-to-Coax Adapters
Right-angle and end-launch configurations with N, SMA, 2.92 mm, 2.4 mm and 1.85 mm connector options by model.
Published family range: 0.32 to 67 GHz Published sizes: WR2300 to WR19
Waveguide Bends
E-plane, H-plane and custom-angle routing with length, radius, flange and finish changes available for selected models.
Published standard range: 1.72 to 110 GHz Published sizes: WR430 to WR10
Directional Couplers
Waveguide or coaxial sample ports, single- or dual-direction monitoring and several port arrangements.
Published range: 1.13 to 40 GHz, WR650 to WR28 Published coupling: 3 to 40 dB by configuration Custom Waveguide Assemblies
Combined straights, bends, flexible sections and end interfaces built from detailed drawings or simple marked-up sketches.
Published scope: L band through W band Drawing, sketch and replacement-part routesInformation that controls the quote
Send the RF and mechanical limits before we release the model
A part number alone might not tell us the flange, connector orientation, power class, sealing requirement or space limits. Add the limits that can’t change.
Function and bandState the component function plus the operating frequency or complete band.
Waveguide sizeUse the WR, R, BJ or WRD designation and confirm the internal section where needed.
End interfacesGive both flange designations, connector type, gender and required orientation.
Power dataSeparate average and peak power. Include pulse conditions when they affect the design.
EnvironmentState pressure, vacuum, temperature, humidity, salt fog or outdoor exposure requirements.
Envelope and routingProvide straight lengths, bend plane, angle, radius, mounting points and blocked areas.
Material and finishConfirm base metal, plating, corrosion protection, paint and non-mating surface needs.
Quantity and recordsList sample and production quantities plus PDF, STEP, RF, inspection or environmental records.
How we make them
Machining, forming, joining and inspection — under one roof
We do CNC milling and turning, waveguide forming and bending, brazing, assembly and dimensional inspection in-house. The actual process depends on the material and shape of your part.
CNC Milling and Turning
Flanges, bodies, transitions, coupling features and mounting details machined to your drawing tolerances.
Forming and Bending
Rigid, preformed and routed sections produced for the required bend plane, angle, radius and installation space.
Brazing and Assembly
Joined assemblies can combine multiple sections and interfaces before dimensional and RF verification.
Dimensional Inspection
We use coordinate measurement for dimensional checks. Tell us in the RFQ if you need inspection reports with delivery.
Measurement and testing services
Tell us what test evidence you need with the parts
We offer RF, antenna, high-power, calibration and environmental testing. Before we release the order, confirm the exact method, frequency range, fixture, acceptance limit and report format you want.
RF Vector and Scalar Measurement
We can measure up to 100 GHz. Tell us the S-parameters you need, frequency points, calibration method and acceptance limits.
Antenna Anechoic Chambers
Use when a supplied horn, probe, feed or assembly needs antenna-related verification rather than component-only RF data.
High-Power Transmitters
State average power, peak power, duty cycle, pulse width, cooling, pressurization and the required proof condition.
Waveguide Calibration Service
Calibration hardware and TRL kit requirements can be added when the component will be used with a VNA test setup.
EMI and EMS Testing
Define the applicable test request and acceptance criteria instead of assuming that every order includes EMC-related evidence.
Environmental Testing
The published list includes temperature, altitude, salt fog and humidity. State the test profile and required record before quotation.
Order support for different situations
New build, replacement or assembly change — same review process
What we need depends on what you’re ordering. Sending the right starting info cuts down on back-and-forth questions.
New Component Selection
Send function, band, WR size, interfaces, power, environment and quantity for a catalog-model shortlist.
Drop-In Replacement
Send the old part number, dimensional drawing, photos and mating hardware. Mark any allowed design changes.
Custom Drawing
Attach PDF or STEP data and identify critical dimensions, datums, tolerances, finish and required inspection records.
Complete RF Path
Send the system route and interface list so several components can be reviewed as one assembly.
