Optimizing the design of a multi-mode communication receiver from performance to manufacturing implementation and yield

Recent trends in cellular radio terminals towards smaller handsets and the proliferation of radio standards around the world created many demands on the future of radio terminals, which should offer multi-mode operation, reduced size, cost, power consumption with increased features. This forces the handset manufacturers to place a premium on printed circuit board (PCB) space, the bill of materials (BOM), and handset differentiation. This paper first reviews various receiver architectures suitable for mobile telephones, specifically related to RF signal processing and after that proposes an optimum multi-mode receiver architecture evaluating the advantages and disadvantages of different possible architectures
