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