General Notes:
1. The CYK-R series of directional couplers consists of three port connectorized devices utilizing special
stripline technology developed for very high directivity over very wide bandwidths.
2. Although the CYK-16R-21G is fully specified down to 2 GHz, it is usable down to 1 GHz with a higher
coupling.
3. This series is ideally suited to precise measurement of forward or reflected power in general purpose
ATE systems, as well as in EW and similar wideband systems where high directivity is essential.
4. Units with performance customized for your requirements are available. Options include coupling
values up to 35 dB and with frequency coverage up to 50 GHz.
5. These units comply with MIL-C-15370 and may be supplied screened for compliance with additional
specifications you designate for military and aerospace applications requiring the highest reliability.
