Channelized receiving technology is an important part of modern electronic warfare and radar systems. It is a core enabling technology that meets the needs of its high frequency band, large bandwidth, and simultaneous multi-channel reception. In this paper, a zero-IF receiver based on microwave photonic is proposed. The center frequency of the optical frequency comb can be adjusted to correspond to the center frequency of the wideband RF signal group. Therefore, the channelized reception of the 3 GHz wideband RF signal is achieved, and each subchannel has a bandwidth of 600 MHz and is directly demodulated into I/Q baseband signal.
