Abstract :
An approximate but highly accurate simple closed-form solution for the element values of noncontiguous lowpass/highpass diplexers has been obtained using broadband matching theory. Excellent results are demonstrated by analysis of several diplexers of degree 10 having a return loss of 26 dB. Suggestions are made for extending the method to other types of noncontiguous multiplexers.<>
