A microwave photonic image rejection mixer (IRM) with large operation bandwidth and high image rejection ratio (IRR) is proposed and demonstrated based on a single dual-drive Mach-Zehnder modulator (DDMZM) and a wavelength division multiplexer (WDM). In the proposed scheme, the two radio-frequency (RF) ports of the DDMZM is driven by a RF signal and a local oscillator (LO) signal, respectively. Two intermediate-frequency (IF) signals are generated by beating the upper sideband and the lower sideband of the DDMZM, respectively. Then, the two IF signals are injected into an electrical 90° hybrid coupler (HC) to realize image rejection. In the experiment, a stable IRR above 60 dB in the RF signal frequency range of 10 GHz to 40 GHz and with a 1- GHz fixed IF signal frequency is achieved. When the IF signal frequency is changed from 1 GHz to 6 GHz and the LO signal is with a fixed frequency of 29 GHz, the IRR can also large than 60 dB.
