Intermediate frequency transformer

If the transformer is mainly used in radio frequency selection and interstage coupling. Frequency selection refers to the selection of useful signal frequencies among many signals and the transmission of functional signals. In AM radios, 465kHz useful signals are selected through intermediate frequency transformers. And coupled to the next level to amplify. At the same time, the signal other than 465kHz is suppressed so that it cannot be transmitted to the succeeding stage.
