Waveguide Gaskets

Waveguide Gaskets – Precision Sealing Solutions for RF and Microwave Applications

Waveguide gaskets are essential components for ensuring optimal sealing and electrical continuity in waveguide systems. bq-microwave supplies high-performance gaskets in circular and rectangular configurations for frequency ranges from L-band to THz, specifically designed for demanding Defense, SATCOM, 5G, and industrial applications.

Key Features

• Circular gaskets for WR284 to WR10 with optimized contact geometry
• Rectangular gaskets for WR650 to WR51 with minimal RF losses
• Materials with wide temperature range and high compressibility
• Reliable EMI/RFI shielding and reduced VSWR impact
• Custom Solutions according to individual specifications

Applications

• SATCOM systems and satellite communications
• Defense and radar technology (FMCW, pulsed)
• 5G/6G infrastructure and mmWave test environments
• HPA/LNA module integration and system assemblies
• High-reliability applications with thermal cycling

Technical Requirements and Material Specification

The gaskets are manufactured from elastomeric and fiber-reinforced materials that provide consistent sealing over repeated assembly cycles. The geometry is optimized for low return loss (minimal dB degradation) while maintaining hermetic sealing against moisture ingress – critical for long-term waveguide system performance in field deployments.
