RF Windows transmit RF or microwave power from a vacuum into an air filled or more likely an inert gas filled transmission line like a waveguide.  It is a resonant cavity designed to maximize RF (radio frequency) power transmission, with minimal loss over a desired frequency range.  RF Windows are used on Linear Accelerators (medical, research & security), Klystrons (medical, security & defense), Traveling Wave Tubes (defense & communication) and other electron beam devices or RF systems that use microwave energy.

We have a number of RF Window designs being sold around the world in L-Band, S-Band, and X-Band frequencies.  We can quickly and routinely make a custom designs to meet your specific needs and we can also turnkey your RF Window design to your exact specifications.

RF Window flanges are typically made out of stainless steel and we supply virtually every flange type including conflats, SLAC or Varian type flanges, LIL, Cover, Choke & Vacuum.  We can also configure your Window to have a mating Weld flange of almost any configuration.

Window materials include Alumina (AL-300, AL-500, AD-94, etc.), Beryllium Oxide, Quartz and more. 

Windows are impedance matched to minimize reflection and achieve low insertion loss and excellent VSWR.  Some designs have a return loss of -40 dB or an equivalent VSWR of 1.02:1 in the selected frequency range.
