General Notes:

1. Merrimac directional couplers are available in a variety of packages to suit most applications. The CRF-A series utilizes the standard

flatpack which is suitable for aerospace applications where size, weight and reliability are important considerations.

2. Applications of directional couplers include monitoring of 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 as in the CBF series of directional couplers.

3. Merrimac Couplers may be ordered with coupling values up to 30 dB covering selected frequency bands up to 65 GHz.

4. These units comply with MIL-C-15370 and can be supplied screened for compliance with additional specifications you specify for

military and aerospace applications requiring higher reliability.
