Abstract
Abstract A compact, high efficiency, highpass, broadband microwave power divider is provided which has an even mode characteristic impedance and an odd mode characteristic impedance which are tapered to equal the characteristic impedance of the output load. The broadband power divider 10 of the present invention includes an input section 1 of conductive material; N tapered sections of conductive material 6, 7, 8 and 9, where N is greater than or equal to 2, extending from and integral with the input section 1; and N output sections of conductive material 2, 3, 4 and 5 each output section extending from and integral with a respective one of the tapered sections 6, 7, 8 and 9.
