are single side band with suppressed carrier. Over the years many architectures such as the filter method, phase shift method/Hartley architecture and Weaver architecture have evolved to achieve single side-band signals in transmitters 10 . In receivers, these architectures are used to achieve image rejection. Among these architectures, the Weaver and Hartley topologies10 are more suitable for integration. This article will provide an overview of recent advancements in receiver and transmitter architectures. It will discuss the system requirements that lead to the selection
