ABSTRACT:
A two way repeater-amplifier for amplifying one or more signals of a first group propagating in a first direction and one or more signals of a second group propagating in the opposite direction is proposed. The repeater-amplifier utilizes a single amplifier disposed to receive signals from first and second filter networks adapted to pass signals within the first and second groups respectively. Third and fourth filter networks are disposed to receive signals from the output of said amplifier and are adapted to pass signals within the second and first groups respectively. Tuned cables cooperate with the networks to route only the first signals through the first network, the amplifier and the fourth network, while other tuned cables cooperate with the networks to route only the second signals through the second network, the amplifier and the third network.
