ABSTRACT:
Methods and apparatus are provided for efficiently coupling singly terminated networks with doubly terminated networks. An isolation network is disposed between a singly terminated network and a doubly terminated network. The isolation network is a three terminal device having an input terminal connected to the output of the singly terminated network and having an output terminal connected to the input of the doubly terminated network. An isolation terminal is provided that receives and dissipates energy reflected from the input of the doubly terminated network, such that substantially no energy is received or seen by the output of the singly terminated network.
