摘要：Aspects of a method and system for FM transmit and FM receive using a transformer as a duplexer 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 receiving and transmitting may be operated in time division duplex mode or simultaneously. A number of windings between a pair of connector terminals of the secondary windings used for transmitting of the radio frequency signals may be less than or equal to a number of windings of the primary windings. A number of windings between a pair of connector terminals of the secondary windings used for receiving of the radio frequency signals may be greater than or equal to a number of windings of the primary windings.
