摘要: A radio-frequency circuit comprises a low-noise amplifier, an NMOS mixer for converting a radio-frequency signal output from the low-noise amplifier into an intermediate-frequency signal, a polyphase filter for removing image noises, and a PMOS mixer for converting the intermediate-frequency signal passed through the polyphase filter into a baseband signal.
