针对60 GHz射频光纤射频/ROF上行链路，研制了一种采用电吸收调制器的TxSoP封装光发射机系统。对改进后的TxSoP进行了噪声系数较小的分析，使其噪声系数降低了15分贝。建立了采用改进的TxSoP的RF/ROF上行链路，在140~800 MHz频率范围内，误差矢量值EVm和信噪比分别为2.2%~3.2%和26db~29db。该链路传输了86路对应的数字有线电视信号，链路总吞吐量为2.6Gbps。C#2008
An optical transmitter system-on-packaging TxSoP with an electro-absorption modulator EAM was developed for 60-GHz band rf with radio-over-fiber rf/RoF uplink. An analysis to develop the TxSoP with a small noise figure was performed so that the noise figure of the modified TxSoP decreased by 15 dB. The rf/RoF uplink with the modified TxSoP was established, and the error vector magnitude EVM and the signal-to-noise ratio SNR of the link were measured between 2.2% and 3.2% and between 26 dB and 29 dB from 140 MHz to 800 MHz, respec- tively. Digital CATV signals corresponding to 86 channels were transmit- ted through the link, and total throughput of the link was 2.6 Gbps. © 2008
