Claim:
1. A directional coupler having a Multimedia Over Coax Alliance (“MoCA”) bypass path, comprising: a housing having an input port, a first output port and a second output port; a first impedance transformer that has a first winding coupled in series between the input port and a first node and a second winding that is positioned to couple with the first winding, the second winding coupled in series between a reference voltage and the first node; a second impedance transformer that has a third winding coupled in series between the first node and a second node and a fourth winding that is positioned to couple with the third winding, the fourth winding coupled in series between the first node and a third node; a resistance having a first end coupled to the third node and a second end coupled to a fourth node; a first inductor in series between the third winding and the second node; a second inductor in series between the fourth winding and the third node; a third inductor and a first capacitor that are disposed in parallel between the second node and the fourth node, wherein the first output port is coupled to the second node opposite the first inductor and the second output port is coupled to the third node opposite the second inductor; and wherein the resistance has a value that is approximately twice the value of a desired impedance of the first output port.
