A balun signal splitter for use in transceiver systems, such as wireless communications systems, including a wide-band balun with a secondary winding for signal splitting between two operating bands (e.g., high-band and low-band) or modes. An example of a balun signal splitter configured for dual-band or dual-mode operation or includes a balun having a primary winding and a secondary winding, the secondary winding having a first port and a second port, a first network coupled to the first port and configured to present a short circuit impedance at the first port at out-of-band frequencies or during out-of-mode operation, and a second network coupled to the second port and configured to present a short circuit impedance at the second port at out-of-band frequencies or during out-of-mode operation. |
