HIGH ISOLATION SIGNAL ROUTING ASSEMBLY FOR FULL DUPLEX COMMUNICATION

摘要

A signal routing assembly accepts a first transmission signal at an input and outputs a substantial portion of the signal at a common port of the signal routing assembly. A second transmission signal is received at the common port and is routed through the signal routing assembly delivered to output of the signal routing assembly. Leakage signals from routing devices leaking the first transmission signal are terminated inside the signal routing assembly. Leakage signals from a divider/combiner are cancelled by reflect signal from at least one reflector device. A transmitter produces the first transmission signal and the signal routing assembly delivers this signal to the common port of the signal routing assembly. In full duplex operation, second transmission signals received at the common port are routed to the output to be applied to a receiver.

主权项

1. An electromagnetic signal routing assembly for effecting two way duplex transmissions, comprising:
a transmission signal input for receiving a first transmission signal; a common port for outputting a portion of said first transmission signal from said transmission signal input and receiving a second transmission signal when present; a transmission signal output for outputting a portion of said second transmission signal when present; a signal divider receiving said first transmission signal from said transmission signal input and dividing said first transmission signal into first and second divided transmission signals; first and second routing devices each having at least first, second and third ports, said first and second routing devices being configured to simultaneously deliver a signal at said first port to said second port and another signal at said second; a signal divider/combiner having first and second divider/combiner ports for receiving said first and second divided transmission output signals and a configuration for combining said first and second divided transmission output signals to output said portion of said first transmission signal to said common port; a signal combiner having first and second combiner inputs for receiving said first and second transmission leakage signals and, when present, for receiving said third and fourth divided transmission output signals, said signal combiner including said transmission signal output, and said signal combiner being configured to introduce a third relative phase shift into signals applied to at least one of said first and second combiner inputs and combine signals applied to said first and second combiner inputs at said transmission signal output at levels within a third amplitude range; and a magnetic biasing device applied to at least one of said first routing device or said second routing device.
