Maury offers waveguide cryogenic terminations in several styles and a wide range of waveguide sizes from WR112 through WR15. The chart below represents a typical sample of the available terminations.
Waveguide terminations are generally calibrated at three frequencies - high, low and arithmetic center - within the applicable frequency range; however, they can be calibrated at any user-specified frequency within the waveguide band. Additional user-specified calibration frequencies are also available as an option.
In addition to liquid nitrogen, these terminations require pressurization with helium gas (not provided) at 2 psi. The MT152A Helium Gas Pressurizing System is available to provide proper regulation of the helium supply.
Model MT7021J (CE) comes with a calibrated WR28 adapter and a universal input power supply.
