DLI Directional couplers for turnkey or custom designs

DLI Directional couplers for turnkey or custom designs

The new series of Directional Couplers from Knowles brand, DLI, provides another example of how high permittivity, temperature stable materials can reduce size/weight and provide excellent performance repeatability.

These Directional Couplers are manufactured using DLI's precision Thin Film technology and offer a great option for microwave systems in commercial, military and space applications. The 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.

• Small Size 
• High Directivity
• Frequency Stable over Temperature
• Solder Surface Mountable
• Excellent Repeatability
• Operating Temp: -55°C to +125°C
• Characteristic Impedance: 50Ω
• Flexible PCB Feed Line Configuration

COTS devices covering C, X and Ku bands offer quick turn solutions in a solder surface mount package. Both 10dB and 20dB coupling values are available within each frequency band both with a common footprint for maximum flexibility.

The devices are designed to provide high directivity, excellent repeatability and stable frequency over the temperature range -55 to +125°C. Designed for a 50Ω characteristic impedance, with common footprints within the bands to provide maximum flexibility and offer a turnkey surface mount solution for high frequency power monitoring. Chip and wire mount devices with the same performance are also available, as are custom solutions to suit individual size and performance parameters.
