Abstract :
Broadband, high-power baluns and matching transformers intended for application in EMC immunity testing are considered in detail. Emphasis is on baluns which are much greater than one-quarter wavelength long at the high end of their operating frequency range. A model for a helical Guanella 4:1 balun is developed and a helical Guanella design is presented. Experimental data which illuminates the action of parasitic modes is presented.
