General Notes:
1. Merrimac offers
directional couplers covering frequencies
from 100 kHz to 18 GHz. They are ideally
suited to monitoring forward and reflected
power with minimal perturbation of the
main line signal.
2. Applications of directional couplers
include monitoring of incident and
reflected power, signal sampling for
control loops and test signal injection
devices in BITE.
3. CRS series directional couplers may be
used back-to-back as dual directional
couplers or ordered with both coupled
ports available as in the CRP series.
4. These units comply with MIL-C-15370
and can be supplied screened for
compliance with additional specifications
you designate for military and aerospace
applications requiring higher reliability.
