The invention discloses an integrated structure of a coherent
channelized receiver. The integrated structure comprises a
laser generation module, a first
optical frequency comb generation module, a second
optical frequency comb generation module, a suppression carrier
single sideband modulation module, an I / Q optical mixing module, two parallel
optical filter modules and a plurality of I / Q
electric coupling modules. According to the invention, the
microwave photon technology is utilized, and compared with the traditional channelization equipment utilizing
electric signal processing, the structure can reduce the
radio frequency interference; by utilizing a
single sideband modulation mode of inhibiting carrier
waves, the processable bandwidth is improved, symmetrical
mirror image componentsgenerated by interaction of signals and original carrier
waves are prevented from being generated, the requirement on an optical band-pass filter is reduced, the integration of an
optical filter is facilitated, and meanwhile, the
signal to
noise ratio of output signals is improved. According to the invention, the structure of the carrier suppression single-
sideband modulator is optimized, the sizeis reduced, and the precision is improved; through the integration of the main body
optical path, the volume of the
receiver is reduced, and the practicability and reliability of the
channelized receiver are improved.
