Abstract :
High-frequency transformer design using the transmission line transformer (TLT) is described. Utilizing transmission line circuit theory, the characteristics of the TLT for different turn ratios are given, and its advantages, including its wideband nature, are discussed. TLT prototypes with turn ratios of 2:1, 3:1, and 5:1 were designed and fabricated. The prototype test results verify the theoretical analysis and also point out the further advantage of compact size, making the TLT approach a promising transformer design alternative for use in high-frequency converters
