Abstract

This study presents a high-linearity K - band single-pole double-throw (SPDT) switch with asymmetric topology in a 65-nm CMOS process for 5G applications. To simultaneously obtain high power-handling capability and high isolation in the Tx and Rx modes, respectively, we propose an SPDT switch using asymmetric topology and the stacked-transistor technique. In both the Tx/Rx modes, the proposed SPDT switch operates with an insertion loss of less than 2.1 dB and isolation better than 22.5 dB in the frequency range 20–25 GHz. At 22 GHz, the measurement results of the input 1-dB compression point (IP1 dB) are 32.5 and 4.7 dBm in Tx and Rx modes, respectively. The chip core size of the proposed SPDT switch is 0.03 mm2.

基于堆叠晶体管的k波段高线性非对称SPDT CMOS开关设计

本研究提出了一种高线性K波段单极双掷(SPDT)开关，采用65纳米CMOS工艺，具有非对称拓扑，用于5G应用。为了在Tx和Rx模式下同时获得高功率处理能力和高隔离，我们提出了一种使用非对称拓扑和堆叠晶体管技术的SPDT开关。在Tx/Rx模式下，所提出的SPDT开关在20-25 GHz频率范围内的插入损耗小于2.1 dB，隔离度优于22.5 dB。在22 GHz时，输入1-dB压缩点(IP1 dB)在Tx和Rx模式下的测量结果分别为32.5和4.7 dBm。所提出的SPDT开关的芯片核心尺寸为0.03 mm2。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
