Enhancing isolation and impedance matching in hybrid-based cancellation networks and duplexers

摘要: Multi-port hybrid-based cancellation networks may be used to enable simultaneous transmit and receive in one or more co-existent communication systems. A multi-port network include a first second quadrature hybrid, two-port network, other circuitry components. The hybrid distinct from the hybrid. filter amplifier connected between hybrids. that is but essentially same as components connection of hybrids networks. These have configuration minimizes signal return loss at least ports network. They addition instead maximizes isolation two
