ABSTRACT:
Circuitry, architectures, devices and systems for multi-band radio communications using a balanced-unbalanced duplexer. An integrated balanced-unbalanced duplexer for multi-band communications may include an unbalanced multi-band port; a first balanced single-band port; a second balanced single-band port; a first unbalanced coupling arm conductively coupled to the unbalanced multi-band port; a second unbalanced coupling arm conductively coupled to the unbalanced multi-band port; a first pair of balanced coupling arms conductively coupled to the first balanced single-band port and electromagnetically coupled to the first unbalanced coupling arm; and a second pair of balanced coupling arms conductively coupled to the second balanced single-band port and electromagnetically coupled to the second unbalanced coupling arm. The architectures and/or systems generally include components embodying one or more of the concepts disclosed herein.
