Enhancing turnkey or custom designs

Offering reduced size and weight using high permittivity, temperature stable materials, the new series of Directional Couplers from Knowles brand, DLI, are manufactured using DLI’s precision Thin Film technology and offer an option for microwave systems in commercial, military and space applications.

Designed for a 50Ω characteristic impedance, they offer a turnkey surface mount solution for high frequency power monitoring. The four port couplers are well suited for high frequency signal monitoring applications where board space is at 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 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, repeatability and stable frequency over the temperature range -55 to 125 ºC. Chip and wire mount devices with the same performance are also available - custom solutions are also available to suit individual size and performance parameters.
