How to Choose the Right Waveguide Pressure Window?
Waveguide Pressure Windows are critical components in many RF and microwave systems, especially when maintaining environmental isolation without compromising signal integrity. Selecting the right seal

Key Factors to Consider:
1.Operating Frequency
Waveguide dimensions and window design must align with your system’s frequency band. At AO Microwave, we offer custom pressure windows covering a wide frequency range — from low GHz bands up to 110 GHz.
2.Flange Type
The flange type determines the mechanical interface and compatibility with your system. Whether you require standard flanges (e.g., CPR, UDR, PDR) or customized flange patterns, we can tailor the solution accordingly.
Common materials include copper and lightweight aluminum, each offering distinct advantages in conductivity, weight, and cost. AO Microwave supports flexible material selection to meet both technical and budgetary needs.
4.Window Thickness and Dielectric Type
The dielectric window material (PTFE) and its thickness affect both transmission loss and sealing performance. We help clients balance RF transparency with mechanical durability through optimized design.
