Baseband Calculations for ISM-RF Receivers

By: Martin Stoehr


Many industrial/scientific/medical (ISM) band radio frequency (RF) receivers use an external Sallen-Key data filter and a data slicer to generate the baseband digital output. This tutorial describes the ISM-RF Baseband Calculator, which can be used to calculate the filter capacitor values and the data slicer RC components, while providing a visual example of the baseband signals.
