Most modern receivers use superheterodyne. It converts the received high-frequency signal into a fixed-frequency intermediate frequency signal through a mixer, amplifies it by an intermediate frequency amplifier, and then sends it to a detector for detection. This type of receiver is relatively complex, but has good receiving performance.
