Mobile devices are widely used for a vast range of applications such as mobile phones,personal digital assistant, personal computers, video games console, etc. However, the performance of these devices is restricted by the support of the network and the mobile functionality and efficiency. Current applications require high data rates and global mobility which can be satisfied with the co-existence and handover between newly developed third generation (3G) or Universal Mobile Telecommunication System (UMTS) standard and current second generation (2G) standards including: Global Standards for Mobile (GSM), Digital Cellular System (DCS), and Personal Communication Systems (PCS). Therefore, recent research in wireless communication has shifted towards achieving a multi-standard terminal, which can support efficiently multiple standards including GSM/DCS/PCS/3G. In this research, the aim is to design and implement a new LNA for a multi-standard mobile receiver based on reconfigurability concept. This research was carried out in two major parts. The first part is to design and implement wide band multi-standard multiband LNAs for two bands of interest (lower frequency band – 800 to 1000 MHz and upper frequency band – 1800 to 2200 MHz). These two bands should cover most of the 2G and 3G standards currently in use worldwide. In this work, the design of LNA based on IDCS topology using wide band approach has been investigated, designed, implemented and approved by means of simulations, and measurement of fabricated ICs. The second part of this research, to develop a single reconfigurable multi-standard multi-band LNA is based on the design of the multi-standard multi-band LNAs. This LNA has the capability to function in two modes of operation, either at lower band or upper band of the 2G or 3G standards.
