A 2-WAY POWER DIVIDER USING COUPLED LINES AND CAPACITANCES

This paper describes the design of a compact two-way power divider com posed of coupled lines and capacitances instead of a quarter-wavelengt h transmission line. The coupled lines are made compact by an approach in which the line lengths of even and odd mode circuits of the couple d lines are shortened by capacitances. Also, the compact coupled lines have an image impedance independent of frequency, as in the case of t ransmission lines. Tests of a trial power divider show that this desig n is effective. In addition, it is shown that a broadband power divide r cascaded from two such coupled line sections can be designed. (C) 19 97 Scripta Technica, Inc.
