General Notes: Merrimac directional couplers available variety packages suit most applications. CRF-A series utilizes standard flatpack which suitable aerospace applications where size, weight reliability important considerations. Applications directional couplers include monitoring incident reflected power,signal sampling control loops test signal injection devices BITE. These Bi-Directional Couplers have both coupled ports available they ordered with coupled port terminated internally series directional couplers. Merrimac Couplers ordered with coupling values covering selected frequency bands GHz. These units comply with MIL-C-15370 supplied screened compliance with additional specifications specify military aerospace applications requiring higher reliability.
