Title:
【発明の名称】高インピーダンス比広帯域トランスフォーマ回路
Document Type and Number:
Japanese Patent JP2001507527
Kind Code:
A
Abstract:
A transformer circuit disclosed performs wideband impedance transformation (matching) and can be used for voltage step-up and step-down applications. The circuit disclosed is comprised of two transmission line transformers and two reactive impedances that compensate the circuit for impedance versus frequency. The circuit disclosed performs a very wideband impedance ratio of 1:9. The circuit may have different turns ratios for T1 and T2 and different values for Z1 and Z2 to accommodate rational, fractional and integer values of transformation up to an impedance ratio of 16:1. The addition of a balun to the output provides a balanced output.
