Directional Couplers

Directional couplers are typically two- or three-port devices for unequally dividing signal between two paths. These can also be used to combine signals with more loss in one input than in the other, with the signal from the high-loss port being routed to only one of the other two ports. This is particularly helpful when there is a need to drop the signal slightly to feed a smaller number of customers.

Point Size (required): Assign a point value to a component based on physical size. With a consistent point value system you will be able to determine how much equipment can fit inside an enclosure. For example, if you have a pedestal rated to hold 30 points worth of components, then you can situate three 2-port taps rated at 10 points each into the box. A fourth 2-port tap would total 40 points, exceeding the rated 30 points of the pedestal.

Tap Value (required)

The forward loss, in decibels. that the signal will drop on the down leg.
