NARROW WALL DIRECTIONAL COUPLERS
These narrow wall couplers are ideally
suited for systems application because of their mechanical simplicity and
high-power handling capabilities. Designed
to operate over the full waveguide frequency band, the units incorporate
Tchebycheff coupling arrays in the common waveguide wall between primary and
secondary sections of the unit. Directivity
is 20 dB typical over the full frequency range.
Special units to meet specific
electrical or mechanical requirements can be furnished on special request.
For power ratings of built-in
termination, refer to ratings on page 33 (-54 series).
Alternate materials and flanges are available.
See flange section. Finish
is instrument gray enamel.
