Choosing the Right Waveguide to Coax Adaptor

Critical Factors for Optimal System Performance Selecting the correct transition is vital for RF system integration services. Our RF & microwave product expert team recommends focusing on these parameters: Frequency Range & Waveguide Size: Match your specific WR-size (e.g., WR-28, WR-42) to ensure the adaptor operates within its dominant mode and covers your required frequency range of RF parts. Connector Interface: We offer a variety of RF connector types (SMA, 2.92mm, 2.4mm) to ensure a high-precision mate with your RF coax cable assemblies. VSWR & Insertion Loss: For lab RF test components, low VSWR is critical to prevent signal reflections that can damage high power RF amplifiers. Orientation & Mechanical Fit: Choose between right-angle or end-launch configurations to meet the SWaP (Size, Weight, and Power) requirements of your aerospace or defense system.

Waveguide Adaptor Technical Questions

What is the typical frequency range for waveguide to coax adaptors?
We provide RF components DC to 110 GHz. Our waveguide transitions are available in all standard WR sizes, providing broadband performance for 5G systems, EW, and satellite communications.
Waveguides inherently handle more power than coaxial lines. Our adaptors are built as high performance RF components to manage the transition of high-power signals without thermal breakdown, protecting your high power RF amplifiers.
Yes. As an RF parts manufacturer, we provide custom RF solutions including specialized flange patterns (e.g., CPR, UG, or custom circular) to ensure a perfect fit for your RF hardware solutions.
