Abstract :
In this paper, modified small asymmetric impedance transformers are suggested. The impedance transformers should transform a real impedance into another one. For this purpose, design technique, being able to transform a complex impedance (admittance) into a real impedance (admittance) only with a transmission-line section, is required. Using this, two types of modified ones are introduced and simulated at a design center frequency of 1 GHz. Their simulation results show considerable bandwidths compared with their sizes.
