Distortion Measurements on Bandpass Filters with Powdered Iron Toroidal Inductors
Abstract
This paper reports the results of measurements of both in-band and out-of-band non-linear distortion for an 11 - 18 MHz bandpass filter which used powdered iron toroidal cores for the inductors. The results are compared with those from a bandpass filter of the same specification using air cored inductors. It is shown that a performance comparable in linearity to the air cored inductor case can be obtained with appropriately sized powdered iron toroidal cores, while still realising to some extent the advantages of magnetic self shielding and smaller volume that are usually associated with the use of toroidal cores....
