Coaxial Directional Couplers

  • Series: C160 Series / C200 Series
  • Category:

M.E.C.’s ultra-flat, directional couplers are compact, in-line devices that exhibit flat coupling over multi octave bands.  The coupling response is finely tailored to yield optimal flatness, directivity, and unit-to-unit tracking, making these versatile couplers useful for both system and laboratory applications.
