ABSTRACT:
A coaxial microwave divider network employing a quarter wavelength long grounded stub for providing support for the center conductor of the divider and also providing improved heat dissipation of the center conductor. Also, this form of stub support permits the center conductor to be supported without a dielectric thereby reducing the insertion loss. Consequently, improved CW power handling performance is possible in comparison with prior designs. Moreover, with the proper choice of the stub admittance level, the input VSWR can also be improved in comparison with a design which employs multi-section matching transformers only at the input.
