In the present technological expansion, the radio frequency integrated circuits in the wireless communication technologies became useful because of the replacement of increasing number of functions, traditional hardware components by modern digital signal processing. The carrier frequencies used for communication systems, now a day, shifted toward the microwave regime. The signal processing for the multiple inputs multiple output wireless communication system using the Metal- Oxide-Semiconductor Field-Effect-Transistor (MOSFET) has been done a lot. In this research the signal processing with help of nano-scaled Cylindrical Surrounding Double Gate (CSDG) MOSFET by means of Double- Pole Four-Throw Radio-Frequency (DP4T RF) switch, in terms of Insertion loss, Isolation, Reverse isolation and Inter modulation have been analyzed. In addition to this a channel model has been presented. Here, we also discussed some patents relevant to the topic.
在当前的技术扩张中，无线通信技术中的射频集成电路因越来越多的功能被现代数字信号处理取代传统硬件组件而变得有用。如今，用于通信系统的载波频率已转向微波频段。使用金属氧化物半导体场效应晶体管（MOSFET）对多输入多输出无线通信系统进行的信号处理已经有很多。在本研究中，借助纳米级圆柱形环绕双栅（CSDG）MOSFET，通过双极四掷射频（DP4T RF）开关进行信号处理，分析了插入损耗、隔离度、反向隔离和互调。除此之外，还提出了一个信道模型。在此，我们还讨论了一些与该主题相关的专利。
