Custom Choke Flanges Tailored to Your Specifications
Off-the-shelf components often limit your system's potential. When your project demands modifications to standard EIA waveguide sizes (WR28 to WR2300) or requires completely non-standard geometries, RALLY executes your exact design requirements.
-
Complex Geometries: Easily handle intricate CNC milling tasks, including specialized choke grooves, O-ring slots, and custom bolt patterns.
-
Full Size Range: Capabilities covering everything from delicate millimeter-wave components to massive industrial waveguide flanges.
-
Frequency-Grade Precision: Machining accuracy up to ±0.01mm ensures the choke groove functions perfectly at your specific operating frequency.
Available Material Options for Your Custom Choke Flanges
Material selection defines the weight, conductivity, and durability of your RF components. RALLY processes the specific international grades listed on your BOM to ensure full compliance with your engineering requirements:
-
Brass (C36000 / C3604 / CW614N): Chosen for its excellent machinability and superior plating adhesion. Ideal for complex choke grooves where surface finish and weight are less critical.
-
Aluminum 6061 (T6): The industry standard for lightweight waveguide components. Offers a balanced combination of strength, corrosion resistance, and conductivity.
-
Aluminum 6082 (T6): Provides higher structural strength than 6061. Excellent for applications requiring enhanced durability in harsh mechanical environments.

Rigorous Inspection for Zero-Defect Waveguide Components
Quality Assurance & Inspection
In high-frequency RF systems, a single micron deviation can compromise your entire signal chain. At RALLY, every component must survive a rigorous verification process designed specifically for waveguide applications before leaving the factory floor. Advanced CMM instrumentation validates that the critical depth and width of the choke trench align perfectly with your CAD specifications. Furthermore, strict surface roughness checks ensure flange faces achieve Ra0.4 or better to eliminate the risk of arcing and guarantee a perfect mating seal. Quality assurance extends beyond physical measurements; comprehensive material traceability reports and RoHS/REACH compliance certificates accompany every shipment, giving you total confidence in the integrity of your supply chain.
Choke Flanges Industry Application
RALLY’s custom waveguide choke flanges serve as the reliable backbone in environments where system failure is not an option. These components are currently deployed across sectors requiring absolute RF integrity:
Radar & Defense
Ensuring breakdown-free operation in high-power airborne and ground-based radar arrays, handling peak pulse power without arcing.
Satellite Communications
maintaining signal integrity within critical uplink amplifiers and complex antenna feed networks where low loss is paramount.
Medical Systems
Delivering precise RF energy containment for high-sensitivity MRI machinery and particle accelerators.
Measurement
Providing superior mating repeatability for calibration kits and laboratory bench setups, allowing for frequent connections without performance degradation.
