DLI (a Knowles Brand) has introduced a new series of Directional Couplers that show how high permittivity, temperature stable materials can reduce size/weight and provide excellent performance repeatability.
Designed for a 50 ohms characteristic impedance, they offer a turnkey surface mount solution for high frequency power monitoring. 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. COTS devices covering C, X and Ku bands offer quick turn solutions in a solder surface mount package with flexible PCB feed line configuration. Both 10 dB and 20 dB coupling values are available within each frequency band both with a common footprint for maximum flexibility.
These small size Directional Couplers are manufactured using DLI’s Thin Film technology and offer a great option for microwave systems in commercial, military and space applications. They are designed to provide high directivity, excellent repeatability and stable frequency over the temperature range -55 to +125 ºC. Chip and wire mount devices with the same performance are also available. Knowles can work with you to develop custom solutions to suit a specific size and performance requirement.
