Abstract

This paper proposes a high isolation of single pole double throw (SPDT) PIN diode switch using switchable dumbbell-shaped defected ground structure (DGS). The proposed SPDT switch was designed for radio frequency (RF) front-end transceiver of antenna array multiple input multiple output (MIMO) in millimeter wave 28 GHz band. The switchable dumbbell-shaped DGS can be switched between allpass and bandstop responses where the bandstop response of the DGS can be utilized as a high isolation in the SPDT PIN diode switch circuit. A simple mathematical analysis is explained in this paper for the bandstop and allpass responses of the switchable dumbbell-shaped DGS. The propose SPDT switch was designed based on Roger RT/Duroid 5880 with 0.254 mm thickness and relative dielectric constant of 2.2. The simulated result showed that the proposed SPDT PIN diode switch produced an isolation of 36.36 dB at 27.3 GHz (center of 28 GHz band), which was 63% higher than the conventional SPDT design.

在毫米波 28 GHz 频段使用可切换哑铃形 DGS 实现 SPDT PIN 二极管开关的高隔离度

提出了一种利用可切换的哑铃形缺陷接地结构(DGS)实现单极双掷(SPDT) PIN二极管高隔离的开关。针对毫米波28ghz频段天线阵列多输入多输出(MIMO)射频前端收发器，设计了SPDT开关。可切换的哑铃形DGS可以在全通和带阻响应之间切换，其中DGS的带阻响应可以用作SPDT PIN二极管开关电路中的高隔离。本文对可切换的哑铃形DGS的带阻和全通响应进行了简单的数学分析。该SPDT开关基于Roger RT/Duroid 5880，厚度为0.254 mm，相对介电常数为2.2。仿真结果表明，该SPDT PIN二极管开关在27.3 GHz (28 GHz频带中心)产生36.36 dB的隔离度，比传统SPDT设计提高63%。
