Aspects of a method and system for using a transformer for FM transmit and FM receive functionality may include communicating data-bearing signals via primary windings of a transformer, wherein secondary windings of the transformer may be utilized for receiving and/or transmitting the communicated data-bearing signals, wherein the secondary windings may be utilized as a load for the transmitting. The secondary windings and/or a power amplifier may be biased for the transmitting by applying an electrical signal at a terminal of the secondary windings, wherein the electrical signal that may be applied at the center terminal may be a biasing voltage. The receiving and the transmitting may be operated in time division duplex mode, or simultaneously. DC signal components for the receiving may be blocked by using a plurality of capacitors.
