General Notes:
1. Merrimac directional couplers are available in a variety of packages to suit most applications. The CRP-N series utilizes the Meri-Pac package which is ideal for
aerospace applications where size, weight and reliability are important considerations.
2. Applications of directional couplers include monitoring incident and reflected power, signal sampling for control loops and test signal injection devices in BITE.
These bi-directional couplers have both coupled ports available but they may be ordered with one coupled port terminated internally in the CBP series.
3. Merrimac Couplers may be ordered with coupling values up to 30 dB and over frequency bands up to 65 GHz.
4. These units comply with MIL-C-15370 and can be supplied screened for compliance with specifications you designate for military and aerospace applications
requiring higher reliability.
