Additional Details:

The DC08-73's key specifications include its frequency range, coupling factor (the ratio of power sampled to the main line power), directivity (the difference between the coupled and isolated port signals), insertion loss, and VSWR (voltage standing wave ratio). It typically uses SMA connectors for easy integration. Proper termination of unused ports is crucial for accurate operation. The power handling capability should also be considered to prevent damage to the coupler. Detailed specifications can be found in the product datasheet.
