我们推出了一款 314 GHz 发射器和接收器芯片组，该芯片组在先进的 SiGe HBT 平台中实现，并具有片上天线。发射器采用有源天线结构，生成的片上信号直接馈入天线。该接收器由一个新颖的分谐波电阻混频器组成，该混频器具有为 LO 端口供电的片上高功率差分信号源。还实施了直接将发射器连接到接收器的测试链路作为表征的参考。该参考电路通过省略外部高频信号源，实现了一种简单而准确的转换损耗和天线增益测量方法。为了进一步促进表征，所使用的片上信号也被单独实现和测试。接收器实现 22.5 dB 转换损耗，发射器在 314 GHz 下生成 -8 dBm 的信号功率。片上端射天线专为发射和接收路径而设计，并利用基板蚀刻技术来提高性能。这项工作展示了使用 SiGe 技术实现完全集成的紧凑型亚毫米波收发器的可行性。
We present a 314 GHz transmitter and receiver chipset which is implemented in an advanced SiGe HBT platform, and which has on-chip antennas. The transmitter uses an active antenna structure, where the generated on-chip signal is directly fed into the antenna. The receiver consists of a novel sub-harmonic resistive mixer with an on-chip high-power differential signal source feeding the LO port. A test link which directly connects the transmitter to the receiver was also implemented as a reference for characterization. This reference circuit enables a simple and accurate measurement method for conversion loss and antenna gain by omitting external high frequency signal sources. To further facilitate the characterization, the utilized on-chip signals were implemented and tested separately as well. The receiver achieves 22.5 dB conversion loss and the transmitter generates a signal power of -8 dBm at 314 GHz. On-die end-fire antennas were designed for both transmit and receive paths, and utilize a substrate etching technology to boost performance. This work demonstrates the feasibility of fully-integrated and compact sub-mmW transceiver implementations using SiGe technology.
