Abstract

A MoCA splitter device may include an input port, a first output port and a second output port, a first transmission line configured to connect the input port to the first output port, a second transmission line configured to connect the input port to the first output port, a first isolation element configured to connect the first transmission line to the second transmission line, a second isolation element configured to connecting the first transmission line to the second transmission line. The first isolation element and the second isolation element are configured to provide an isolation level between the first output port and the second output port that is less than a predetermined isolation level of about less than 16 dB in a MoCA frequency band.

A MoCA splitter device, comprising:

an input port;
a plurality of output ports;
a plurality of splitters configured to be connected between the input port and the output ports;
wherein each splitter comprises a first transmission line, a second transmission line, a first isolation element configured to be connected between the first transmission line and the second transmission line, and a second isolation element configured to be connected between the first transmission line and the second transmission line;
wherein the second isolation element is located downstream from the first isolation element;
wherein the splitter device comprises a multi-stage splitter device;
wherein the splitter device comprises a Microstrip splitter device;
wherein the splitter device includes a Wilkinson circuit configuration;
wherein the first isolation element and the second isolation element are configured to provide an isolation level between each of the output ports of less than a predetermined isolation level in a MoCA frequency band;
wherein the first isolation element and the second isolation element are configured to provide an insertion loss between the input port and each of the output ports of less than a predetermined insertion loss level;
wherein the first isolation element and the second isolation element are configured to provide a substantially uniform isolation level between each of the output ports;
wherein the predetermined isolation level is about 16 dB or less;
wherein the MoCA frequency band is 1125-1675 MHz;
wherein the predetermined insertion loss level is about 8 dB or less;
wherein a type and a value of the first isolation element and a type and a value of the second isolation element are selected to configure the isolation level between each of the output ports;
wherein the type and the value of the first isolation element and the type and the value of the second isolation element are selected to configure the insertion loss between the input port and each of the output ports;
and
wherein the type and the value of the first isolation element and the type and the value of the second isolation element are selected to configure the substantially uniform isolation level between each of the output ports.
