Abstract

PURPOSE:To eliminate nearly completely the reflected wave component by providing a line length difference which gives a 90-degree phase difference, to obtain a good-quality conversion output signal with a good conversion efficeincy, and also to reduce the insertion loss by 3dB to obtain a good-quality filter and delay line.
