Abstract

A study using a PIN diode switched version of a linear balanced duplexer (LBD) for use in a 7 T (298 MHz) magnetic resonance imaging application is described. A prototype LBD TR switch was fabricated on FR-4 and modeled using a complex impedance model of the PIN diode and shows good insertion loss and isolation performance at 298 MHz. The scattering matrix analysis presented in the paper is verified with experimental data that show good agreement with the model.

基于PIN二极管的7 T MRI收发开关

本文描述了在7 T (298 MHz)磁共振成像应用中使用PIN二极管开关版本的线性平衡双工器(LBD)的研究。在FR-4上制作了一个LBD TR开关原型，并利用PIN二极管的复杂阻抗模型进行建模，在298 MHz下显示出良好的插入损耗和隔离性能。用实验数据验证了本文提出的散射矩阵分析方法，结果与模型吻合较好。
