Abstract:
A circuit for a wideband electrical balance duplexer (EBD) may include a first impedance element and a second impedance coupled between a first and a second node and a second and a third node of the bridge circuit, respectively. An antenna may be coupled between the first and a fourth node of the bridge circuit to receive and transmit RF signals. A balancing network may provide an impedance substantially matching an impedance of the antenna. The balancing network may be coupled between the third and the fourth node of the bridge circuit. The first or the second impedance elements may facilitate balancing the bridge circuit. One or more output nodes of a transmit path may be coupled to an input node of the bridge circuit. One or more input nodes of a receive path may be coupled between the second and the fourth node of the bridge circuit.
