Wideband power divider using a coaxial cable 2:1 transmission line transformer

초록

This paper describes a wideband power divider using a new type of transmission line transformer (TLT) to change impedance from 50 to 25 Omega. A prototype of the power divider to connect two 50-Omega coaxial cables to the 25-Omega output ports of the proposed TLT was fabricated. The reflection characteristics of the proposed TLT were less than -15 dB over the range 54-907 MHz. The reflected power of the power divider was less than -14 dB, and the relative amplitude and phase difference between two outputs of the power divider were within +/- 0.15 dB and +/- 1.0 degrees over the range 100-900 MHz.
