Abstract:A wideband microwave photonic in-phase and quadrature (I/Q) mixer is proposed and experimentally demonstrated. In the proposed system, the 90-degree phase difference of the I/Q mixer is achieved by implementing phase modulation and intensity modulation in I and Q channels, respectively. Experimental results show that the proposed I/Q mixer has the advantages of excellent 90-degree phase balance (<&plusmn;3o) and a small amplitude imbalance less than 1 dB in a wide radio-frequency bandwidth from 10 to 36 GHz. &copy; 2018 IEEE.
