Directional Couplers For Signal Monitoring In C, X And Ku Bands


Knowles brandDLI has launched new small sized 10dB and 20dB directional couplers for C, X and Ku bands. The devices offer a great option for microwave systems in commercial, military and space applications.

“Made using thin-film high-permittivity temperature-stable materials, these four port couplers are excellent for high frequency signal monitoring applications where board space is a premium and quality power detection or injection is required”, said DLI in the Press release.

The small directional couplers are designed for a 50Ω characteristic impedance and support various PCB feed line configurations.

“The devices are designed to provide high directivity, excellent repeatability and stable frequency over the temperature range -55º to +125 ºC”, said DLI.

Chip and wire mount devices with the same performance are also available, as are custom solutions.
