SUPPRESSION OF SPURIOUS EMISSIONS.

Abstract

The feasibility of using open periodic structures in microwave filters was studied for suppressing spurious and harmonic energy generated by high power transmitters. An L-band breadboard model was fabricated and tested at both low and high power and the experimental results validated the theoretical analysis. This filter is capable of handling 2.5 megawatts of peak power and has a spurious harmonic rejection of at least 50 db over the entire measured stop band. The techniques used in this filter however are capable of peak power levels of at least 10 megawatts. When this microwave filtering concept is fully developed, filters can be produced and installed in high power radar systems at a cost substantially less than of using other state-of-the-art filters with the same electrical characteristics.
