Dolph Microwave
Seamless Flexible Waveguide Assemblies
Use a seamless flexible section to reach a flange or route around limited space. Choose the size and length from the RF requirements, then check the bending route and pressure conditions.
- Combined model coverage
- 1.13–50.1 GHz
- Bending directions
- E & H planes
- Listed maximum pressure
- 30 PSIG
Before you order
Specify the installed shape, not only the length
Routing and support
Show the fixed points and flange faces on a simple sketch. This helps distinguish a routing adjustment from repeated movement during operation.
Loss and average power
The WR650 row lists 0.12 dB/m and 20 kW average power. The WR22 row lists 2.7 dB/m and 0.05 kW. Use the row for your operating band.
Core, jacket and temperature
The table lists Brass / BeCu cores with silicone jackets. The construction description also offers neoprene and states −20°C to +100°C; confirm the jacket for your order.
The flexible waveguide selection guide covers routing and bend requirements. For the installed run, compare waveguide supports and hangers.
For the rest of your setup
Do the flange faces also need to twist?
Bending in the E-plane or H-plane does not establish a torsion rating. If the ends need rotation relative to each other, compare the twistable range and specify the angle.
