In the existing microwave photons system, low-cost, high-performance and arrayed electro-optic conversion components become one of the technical bottlenecks that restrict the application of microwave photons. A four channel direct modulation electro-optic conversion module based on photoelectric hybrid packaging technology is designed. The module integrates a variety of functional chips and realizes the function of converting four channels of 2~18 GHz radio frequency signals into optical signals. The test results show that the module achieves 18 GHz electro-optic modulation bandwidth, 9 dB insertion loss, less than 30 dB noise coefficient and more than 10 dBm input third order intersection3(IIP3). While ensuring high-performance electro-optical conversion, it can effectively reduce package size, reduce system weight and improve system integration, which is conducive to the array application of microwave photons technology.
