HIGH POWER & EXTRA HIGH POWER
TERMINATIONS
Description
MEC Rectangular Waveguide High Power 80-H and
Extra High Power 80-E Terminations are constructed of finned aluminum waveguide containing
high temperature absorbing material in intimate contact with the waveguide walls for good
heat transfer. Standard units of 1,000 W or less are cooled by free air convection; for
rating greater then 1,000 W, forced air must be used. For higher powers, shorter length,
or lower temperature rise, an integrally mounted fan and ducted housing may be
supplied in provide forced air cooling. VSWR is 1.05 max. for operation over the full
waveguide frequency band.
Designed to withstand conditions of extreme
temperature and thermal shock, these terminations are ideal for use in high power systems
as dummy antennas to permit testing, tuning , and maintenance without radiating RF power.
Finish is Chemical Film, per MIL-C-5541, Class 3,
followed by high temperature black epoxy enamel.
A power sampling probe can be supplied as a separate
unit to monitor power. Typical sampling flatness is ± 0.5dB across the entire band for
levels from 30 to 50 dB.
