A Broadband Planar N-Way Combiner/Divider

The experimental and predicted performance of the new broadband planar N-way combiner/divider is presented. The advantage of this combiner/divider over those previously published is that it can be realized in a planar structure. Experimental data on the planar combiner/divider for N=4 and N =7 indicates an average isolation of 20 dB between the N ports from 8 to 12 GHz, and compares favorably with analytic predictions.
