Abstract :
Quarter-wave transformers are fundamental elements for numerous circuit designs. Due to the property of a transmission line, circuits designed with the quarter-wave transformers inherently have spurious passbands. Aperiodic stubs on a microstrip line are exploited to implement a low-pass quarter-wave transformer in this paper. Such a joint design is expected to solve the problems of spurious passbands, and enhance the degree of integration in RF and microwave systems.
