Knowles DLI

SMT Directional Couplers

Knowles DLI's SMT directional couplers feature an operating temperature range of -55°C to +125°C

Image of Knowles Dielectric Labs' SMT Directional CouplersKnowles DLI’s surface-mount directional coupler series span the frequency spectrum of C, X, and Ku bands. Both 10 dB and 20 dB 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.

Features
  • Small size
  • Frequency stable over temperature
  • Solder surface mountable
  • Excellent repeatability
  • Operating temperature: -55°C to +125°C
  • Characteristic impedance: 50 Ω
