Connect waveguide components to RF antennas using precisely aligned flanges (e.g., CPR-229) to minimize signal loss. Seal joints with conductive gaskets or copper tape to maintain an airtight, low-VSWR interface (<1.2:1 ideal). Use a torque wrench to tighten flange bolts to the specified value (e.g., 25 in-lbs) for consistent electrical continuity. ​​Waveguide and Antenna Interface […]

Waveguide duplexers are crucial for allowing a single antenna to simultaneously transmit and receive signals, often operating in frequency ranges like 3.5-4.2 GHz. They use internal filters to provide high isolation, typically over 30 dB, preventing powerful transmitted signals from overwhelming sensitive receivers, which is vital in radar and cellular systems.
