Merrimac offers a wide variety of 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. NOTES: 1. Tolerance on 3 place decimals 2. Dimensions in inches over millimeters. .010(.25) except as noted. Package Outline - CRS-10-165 NOTES: 1. Tolerance on 3 place decimals 2. Dimensions in inches over millimeters. .010(.25) except as noted. 25Mar96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 |
