PCB DISTRIBUTED TRANSMISSION LINE TRANSFORMER FOR VOLTAGE COMBINING TECHNIQUE

摘要

A PCB(Printed Circuit Board) distributed transmission line transformer for a voltage combining method is provided to be formed on a PCB instead of being formed as an IC(Integrated Circuit) on a semiconductor substrate, thereby obtaining high Q-factors while length of the transmission line gets bigger. A primary transmission line(231) and a secondary transmission line(232) are formed on a PCB(310). Both ends of the primary transmission line(231) are connected to an amplification stage(210) having differential input as active elements on the PCB(310). Connection between the primary transmission line(231) and the amplification stage(210) is carried out through wire bonding processes(231a).
