Knowles – Directional Couplers

High frequency directional couplers incorporating Knowles DLI brand’s high permittivity ceramic materials. Devices provide small size and minimal performance variation over temperature.  Well matched for monitoring incident and reflected power.

DLI’s surface mount directional coupler series span the frequency spectrum of C, X and Ku bands. Both 10dB and 20dB coupling values are available within each frequency band both with a common footprint for maximum flexibility. These couplers incorporate DLI’s low loss high permittivity ceramics which provide small size and temperature stability. These couplers offer a turnkey surface mount solution for high frequency power monitoring. Custom solutions are also available
