High Power Windows for Microwave and Millimeter-Wave Applications

Calabazas Creek Research, Inc. has designed RF windows from L-Band to W-Band at power levels from a few watts to more than 100 MW. Recent designs include a TE01 window for 200 MW pulsed operation at 1.3 GHz and a 100 MW window at X-Band using single crystal sapphire.

Interested parties should contact Dr. Lawrence Ives at Calabazas Creek Research, Inc.
