Microwave structural components are the physical, often metallic or dielectric, parts that shape, guide, or confine electromagnetic waves in the microwave frequency range (typically 300 MHz to 300 GHz). They are the mechanical hardware of a microwave system — not the active electronics (like amplifiers or oscillators) and not complete assemblies (like a radio or radar unit).

Key characteristics: Passive – they do not generate or amplify signals on their own.Precision-machined – their dimensions directly affect electrical performance (e.g., a fraction of a millimeter change in a waveguide alters its cutoff frequency).Customizable – often designed for a specific system integration.

RF Resonant Cavities – These are critical for filtering and frequency control in microwave systems. We produce cavities tailored to specific frequency bands, materials, and dimensional tolerances, ensuring optimal performance in demanding environments such as satellite communications and medical linear accelerators.

Waveguides – Our waveguides are manufactured in various cross-sectional shapes (rectangular, circular, or double-ridge) and materials (aluminum, copper, brass, or custom alloys). Each waveguide is designed to minimize insertion loss and maximize power handling, based on your exact mechanical and electrical specifications.

We specialize in the precision manufacturing of microwave structural components, focusing exclusively on custom-engineered parts rather than complete microwave assemblies. Our expertise lies in producing high-quality, application-specific components such as RF resonant cavities, waveguides, and antennas. We do not manufacture finished microwave products like transceivers, amplifiers, or complete radar systems. Instead, we serve as a trusted partner for clients who require reliable, custom-built microwave structures to integrate into their own systems.

Comparison of cavity dimensions for millimeter-wave and microwave

Frequency band	frequency range	wavelength	waveguide width	resonant pillar	wall thickness
microwave cavity	1GHz - 30GHz (L, S, C, X, Ku, K band)	10mm - 100mm	20mm - 40mm	2mm - 10mm	2mm - 5mm
millimeter wave cavity	30GHz - 75GHz (Ka, Q, V, E band)	4mm - 10mm	10mm - 20mm	0.5mm - 2mm	0.5mm - 2mm m
submillimeter wave cavity	90GHz - 300GHz+(W, D, G, THz band)	1mm - 3.3mm	3mm - 8mm	0.1mm - 0.5mm	0.3mm - 1m

Antennas – From patch antennas to horn antennas and array feeds, we fabricate microwave antenna structures that meet unique gain, beamwidth, and polarization requirements. All parts are produced with tight tolerances and surface finishes suited for high-frequency operation.

We do not offer off-the-shelf products. Every component is made to order, following your engineering drawings or performance targets. Our manufacturing capabilities include CNC machining, EDM, brazing, and precision plating. Quality assurance includes vector network analyzer testing for passive intermodulation (PIM) and return loss where applicable.

By focusing only on microwave structures and not final products, we avoid the constraints of standardized assemblies. This allows us to deliver fully customizable, high-performance components that fit seamlessly into your subsystem design. Whether for defense, aerospace, telecommunications, or research, we produce the parts you need – nothing more, nothing less
