GENERAL INFORMATION
The CD Series Directional Detectors are directional
couplers with and integral detector. They are used
for monitoring power without disturbing the main

using high sensitivity detector diodes and high
directivity couplers. They are octave band units, but
can be custom tuned to any narrow frequency band
in order to achieve flatter response.
