Mega Industries produces Gas Barriers for rectangular waveguide in sizes ranging from WR-28 to WR-2300. We typically cover a frequency range of 0.32 GHz to 40 GHz. The newest dielectric materials are utilized for these extremely compact gas barriers. This assures minimum transmission loss and maximum power handling.
For optimum performance, we recommend that your microwave feed system be maintained under a slight positive pressure. This prevents the entrance of moisture or other contaminants. These units are less than 1.00″ thick in WR650 through WR975 and 2.00″ in WR1150 through WR2300, and are available with or without gas ports.
