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.

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.

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.

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.

Bands we do customL, S, C, X, Ku, K, Ka and millimeter-wave up to W band.
Build optionsOxygen-free copper, brazed construction, flexible sections and custom end flanges.
Finish optionsSilver or gold plating available where the design calls for it.

Information 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.

About the supplier

Check who you’re buying from before you place the order

Use the company, product, manufacturing and support pages to verify what we do. Product specs and compliance are model-dependent — not blanket across everything.

Founded in 2001We design and manufacture microwave components and antenna feed systems. Factory in Xi’an, China.
ISO 9001:2015Our quality system covers waveguide component design, manufacture and sale.
One-Year WarrantyCovers material and workmanship defects from delivery date. Full terms on our website.
Model DocumentsMost product tables have PDF datasheets and STEP drawing links you can download.
RoHS by ModelRoHS or RoHS+REACH status is shown on selected product tables. Check per model.
Direct Engineering InputRFQ review can start from a catalog model, drawing, STEP, sketch or existing replacement part.

Send us your RFQ — no form needed

Email your drawing or specs. We’ll review and quote.

Attach whatever engineering data you have. We can review a catalog model, replacement part, modified interface or complete waveguide assembly — email is fine.
