Abstract
A Docsis-MoCA coupled line directional coupler includes an input port, an output port, a coupled port, and a termination port. A first track connects the input port to the output port and a second track, which may be substantially parallel to the first track, connects the termination port to the coupled port. The first track and the second track are configured to form a variable coupling length so as to control, for instance, an isolation level between the output port and the coupled port to be less than a predetermined isolation level in a MoCA frequency band.
