An integrated duplexer based on electrical balance is described. The duplexer module includes a hybrid transformer. The hybrid transformer includes a primary coil and a secondary coil. The primary coil is coupled between an output of a power amplifier and an antenna. The secondary coil is coupled between an input of a low noise amplifier and ground. The duplexer also includes a balancing impedance that is coupled between the primary coil and the secondary coil. |
