Abstract: With the efforts of innovative consortium, wireless local area network (WLAN) became alternative standard in wireless local area networking applications. From the beginning the data rate keeps pace from mega bits per second (Mbps) up to giga bits per second. The ease of adaptability of WLAN protocol and the need for high data rate communication system made a reason to develop a solution and to incorporate real time wireless transceivers on network interface cards and FPGAs. Over the past decade, the RFIC technology became the hive of communication industry, with the proliferation of 802.11 a, g, n, ac, ad wireless protocols. The applications like ultra wide band (UWB), digital TV broadcasting and global positioning system found their way to main-stream gadgets. With the design preferences such as interconnect parasitics, interconnects and coupling between devices the passive elements must be precisely designed. In this article, novel requirements of low noise amplifier (LNA) design for 2.4 GHz application with noise modelling is presented.
