difference between output ports as well as consistent electrical performance over broad frequency ranges. To demonstrate the technique, an experimental design was developed for frequencies from 2.7 to 6.6 GHz with better than 15 dB isolation between ports and tightly matched phase and amplitude characteristics between the two output ports.Ĭhallenges in fabricating compact quadrature power splitters include maintaining the tight 90-deg.

The current project details the use of a new type of composite right/left-handed transmission line (CRLH TL) constructed in microstrip by Minkowski loop-shaped complementary split ring resonators (M-CSRRs) to form an extremely compact quadrature power splitter with low insertion loss and high isolation. 1,2 Because of the wavelength dependence of microstrip and stripline circuits, however, maintaining the small size of a printed quadrature power splitter can be challenging. They can be used, for example, to realize amplifiers, phase shifters, and balanced mixers for receivers and transmitters. difference between output ports, are useful components in communications systems applications.
