In today's world of miniaturization, there is ever-increasing industry pressure to reduce the cost of communication chips. This pressure has driven designers to develop transceivers with higher levels of integration. Achieving the goal of maximum integration between the antenna and data output is not as trivial as replacing external components with on-chip components. Instead it requires a complete overhaul of the front-end design. Traditional radio designs that use excessive bills of materials are seen as less of a solution today where power, size and cost is critical. This has resulted in new radio architectures with fewer off-chip components.
