Abstract : A proposed shipboard tran mission system involved the connection of transmitters covering the 1f and 2-6 mc/s bands for simultaneous operation on a common antenna through available complementary filters. A broadband transformer was required to perform the necessary impedance transformation between transmitter and filter at a p wer level of 2500 watts. The approach given here concerns the design and analysis of eleven- and thirteenelement, linearly tapered, M-derived, low-passfilter, lumped-element transformers. The results of tests conducted on an experimental model of an eleven-element transformer constructed of receiver-type components are compared with the analytical data. (Author)
