Harmonic-rejection type of even-harmonic mixer (EHMIX) for zero-IF receiver is proposed in this paper・ Two polyphase structures are introduced and compared for harmonic signal rejection of the EHMIX. It is shown that no signal weighting is needed for both the structures, unlike harmonic-rejecting type of switching mixers. The two structures may use polyphase LO signals with 45°or 90°phase shift in order to 2fRF not to downconverter to baseband. For I/Q demodulation, EHMIX requires LO signals with 45°of phase difference. So the 45°LO system may have a smaller hardware size.
