摘要

提出了一种新的单稳态收发器拓扑，该拓扑利用基于二极管的混频器，工作频率为143.8至158.1 GHz。该体系结构避免使用耦合器和相关的限制。因此，它可以节省空间并最大限度地减少损失。信号直接从VCO通过一个二极管连接的npn晶体管传播到天线，该晶体管执行混合。对于传输的信号，只有小于1.8 dB的小插入损耗。整个混频器电路仅消耗65 x 260µm2的面积。此外，收发器的概念显著提高了信噪比。

A Compact Monostatic Transceiver Topology Using a Diode-Based Mixer

A novel monostatic transceiver topology that makes use of a diode-based mixer and operates from 143.8 to 158.1 GHz is proposed. The architecture avoids using couplers and the associated limitations. Hence, it allows to save space and minimizes losses. The signal travels directly from the VCO to the antenna through a diode-connected npn transistor, which performs the mixing. For the transmitted signal, solely a small insertion loss of less than 1.8 dB occurs. The complete mixer circuit only consumes an area of 65 x 260 µm2. Furthermore, the transceiver concept significantly improves the signal-to-noise ratio.
