Abstract
The present disclosure is directed a directional Multimedia over Coax Alliance (MoCA) filter. The MoCA filter can include a first port and a second port. Additionally, the MoCA filter can include a bidirectional path and a unidirectional path in parallel between the first port and the second port. Further, the unidirectional path can include an active isolator or a passive isolator.
Claims20
A Multimedia over Coaxial Alliance (MoCA) filter comprising:
- a first port;
- a second port;
- and
- a bidirectional path and a unidirectional path in parallel between the first port and the second port.
1 more element
A Multimedia over Coaxial Alliance (MoCA) filter comprising:
- a first port;
- a second port;
- a bidirectional path communicating an upstream signal and an expanded downstream signal between the internal port and the first port;
- and
- a unidirectional path solely communicating the expanded downstream signal from the first port to the internal port,
- wherein:
- the bidirectional path includes a first low-pass filter device serially connected to a second low-pass filter device;
- and
- the unidirectional path includes a first band-pass filter device serially connected to an active isolator device and a second band-pass filter device.

- wherein:
- the bidirectional path includes a first low-pass filter device serially connected to a second low-pass filter device;
- the unidirectional path includes a first band-pass filter device serially connected to a passive isolator device and a second low-pass filter device;
- the passive isolator device comprises a circulator;
- a first node of the circulator receives the expanded downstream signal;
- a second node of the circulator isolates a MoCA signal from the first port;
- and
- a third node of the circulator is terminated.
