Surface Mount Couplers and Wilkinson Power Dividers from DLI


  4-18GHz SM Directional Couplers 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 formaximum 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.
