Abstract
A transceiver comprising a plurality of components coupled to one another to form a transmit path and a receive path and a balun. The balun comprises a primary inductor, two pairs of secondary inductors and switched impedance modules. The primary inductor is configured to couple to the communications medium at an unbalanced port end. The two pairs of secondary inductors are each configured to electromagnetically couple with the primary inductor and each providing an associated one of two balanced, ports coupled to components forming the transmit path and the receive path. The switched impedance modules are each coupled to a corresponding one of the two pairs of secondary inductors to switchably split into a virtual open, one pair of secondary inductors associated with an inactive, one of the balanced ports and to couple another pair of secondary inductors associated with an active one of the balanced ports either to each other or to a virtual ground.
