“…This how ever will introduce similar problems to that faced by the direct conversion receivers which include DC offset problem and the LO leakage problem. Different techniques have been explored to improve the performance of the weaver architecture [9][10] and image rejection of 40dB and 74mW power consumption has also been achieved [11].…”

This paper presents an analysis of the three popular image reject architectures used in radio receiver design. The SAW-filter based image reject architecture is the simplest to implement and has the lowest power consumption while the weaver is the most complex with the highest power consumption. The Hartley architecture which utilizes half the number of mixers used in the weaver architecture does not consume as much as the weaver architecture but is not as efficient due to the use of the 900phase shifter. The three architectures are optimized for various design specifications. The receiver design with power constraints is better realized using the SAW filter while the receiver with portability as its highest priority is better realized using the weaver architecture. The architecture implemented for any particular radio design is determined by the receiver specification with the highest priority.

This article presents an overview of digital radiocommunications with emphasis on wireless personal communications. The main objective of wireless personal communication is to allow the user access to the capabilities of the global network at any time and without regards to location and mobility. Digital radio, used extensively in second‐generation and the evolving third‐generation systems, considerably improves the quality of the cellular system and enhances the services available to the mobile subscribers.
