Abstract

Key blocker requirements of software defined radio receivers are identified from first principles. Three challenges are derived from these requirements, the need for passive filter banks or tunable passive filters, a very highly linear RF front-end and a high performance analog-to-digital converter. Each of these challenges is analyzed regarding possible solutions in the context of state-of-the art technology.
