Getting Started with a Radio Design

By: Martin Stoehr

Abstract: The process of designing a radio system can be complex and often involves many project tradeoffs. With a little insight, balancing these various characteristics can make the job of designing a radio system easier. This tutorial explores these tradeoffs and provides details to consider for various radio applications. With a focus on the industrial, scientific, medical (ISM) bands, the subjects of frequency selection, one-way versus two-way systems, modulation techniques, cost, antenna options, power-supply influences, effects on range, and protocol selection are explored.
