摘要

本文报道了1 m 220-260 GHz可调谐载波无线链路的特性和性能评估，该链路采用0.13 μ m SiGe HBT技术实现高集成直接转换正交TX/RX模块，ft/fmax为350/550 GHz。在15 GHz的中频带宽限制下，BPSK/QPSK调制方案实现的最大数据速率分别为35 Gbps和65 Gbps, EVM分别为28.9%和31.5%。进一步发现，当前链路性能不受awn相关信噪比的限制，而主要受大操作带宽相关射频前端缺陷的影响。

Performance Evaluation of a 220–260 GHz LO Tunable BPSK/QPSK Wireless Link in SiGe HBT Technology

This paper reports on characterization and performance evaluation of a 1-m 220–260 GHz tunable carrier wireless link with highly-integrated direct-conversion quadrature TX/RX modules implemented in 0.13µm SiGe HBT technology with ft/fmax of 350/550 GHz. Under limited IF bandwidth constraints of 15 GHz, the maximum achieved data rates for BPSK/QPSK modulation schemes are 35 Gbps with an EVM of 28.9 % and 65 Gbps with an EVM of 31.5 %, respectively. It is further found that the current link performance is not limited by the AWGN-related SNR but mainly affected by the RF front-end imperfections related to large operation bandwidth.
