Construction Techniques for LC Highpass and Lowpass Filters Used in the 1 MHz to 1 GHz Frequency Range

Abstract

This technical note describes construction techniques for building passive LC highpass and lowpass filters whose intended use spans several octaves of bandwidth. It examines limitations in the frequency domain of the two basic components, inductors and capacitors, used to build these filters, the unwanted effects of the distributed reactance of opposite sign to the wanted within these components and the electro-magnetic coupling between these components when used to build a filter. The impact these unwanted characteristics have on the filter's overall performance is then examined. Recommendations are given on the various steps that may be taken to reduce these unwanted effects minimizing the deviation from a filter's ideal performance.
