Flexible and scalable front-end tuner for software defined radio: Page 5 of 5

April 11, 2017 //By Nazzareno Rossetti, Kishore Racherla, Adam Heiberg
Traditional radio receivers require as many radio receiver chips as there are standards. In contrast, Software Defined Radio (SDR) architectures perform the baseband processing using software, enabling reception of a wide range of radio standards with a single radio platform. This article discusses different ways to handle the SDR baseband processing and proposes a cost effective, flexible and scalable implementation that best actualizes the potential of SDR.

We looked at a highly integrated solution which handles two standards, each with its own baseband processor and front-end. We found that this solution lacks the flexibility needed to fully implement SDR. The MAX2175, Maxim Integrated’s World Band Radio receiver, was presented as a superior alternative. This advanced RF to Bits automotive radio tuner enables the most flexible and scalable SDR implementation and reduces cost, by more efficiently utilizing the multicore application processor.
