摘　　要：针对光载无线通信(RoF)系统对高增益、小型化光接收模块(ROSA)的需求,基于混合集成技术,设计并制作了一种高增益的四通道ROSA器件,尺寸为20.0 mm×14.0 mm×5.9 mm。模块内集成了低噪声放大器(LNA)芯片以提高射频信号增益,建立了射频信号传输电路,并对器件特性进行了仿真分析。经测试,器件的射频信号增益达14 dB,-3 dB带宽为23 GHz,在1550 nm波长的入射光下,器件的响应度为0.81 A/W,相邻信道之间的射频信号串扰小于-40 dB。该模块对于减小RoF系统的体积和功耗具有重要意义。To meet the requirements of a high-gain and miniaturized receiver optical subassembly(ROSA)for radio over fiber(RoF)systems,a four-channel ROSA device with a size of 20.0 mm×14.0 mm×5.9 mm is designed and fabricated based on hybrid integration technology.Low noise amplifier(LNA)chips are integrated into the module to improve the radio frequency(RF)signal gain,and the RF signal transmission circuit is established to simulate the performance of the device.The RF signal gain of the device is 14 dB,the-3 dB bandwidth of the device is 23 GHz,and the responsivity of the device is 0.81 A/W at the incident light wavelength of 1550 nm.The crosstalk of RF signals between adjacent channels is less than-40 dB.This module has important significance for reducing the volume and power consumption of the RoF system.
