On the Direct Conversion Receiver
Abstract
Increased pressure for low power, small form factor, low cost, and reduced bill of materials in such radio applications as mobile communications has driven academia and industry to resurrect the Direct Conversion Receiver (DCR). Long abandoned in favor of the mature superheterodyne receiver, direct conversion has emerged over the last decade or so thanks to improved semiconductor process technologies and astute design techniques. This paper describes the characteristics of the DCR and the issues it raises. brief description of alternative and well-established receiver architectures, this paper presents the direct conversion reception technique and highlights some of the system-level issues associated with DCR.
