.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Lead dimensions apply only at body.
4. All unmarked pins are case ground.
General Notes:
1. Directional couplers find application in monitoring
incident and reflected power, signal sampling for
control loops, as well as signal injection devices in
BITE systems. These Directional Couplers may be
used back-to-back as Dual Directional Couplers or
ordered with both coupled ports available configured
as Bi-Directional Couplers as in the CRP-N series.
2. Merrimac Couplers may be ordered with specific
coupling values up to 30 dB and over selected
frequency bands up to 18 GHz.
3. All Merrimac Couplers 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.
