A STUDY OF WIDEBAND N-WAY POWER DIVIDERS.
Abstract
An N-way power divider which may serve as an array feeding system, splits the input signal into N equiamplitude and equiphase output signals as required. The study first emphasizes the transmission-line-type devices. A symmetric N-way junction followed by cascaded transmission-line segments and the associated interconnecting resistors (referred to as isolation resistances) compose a wideband power divider. The usual design requirements for the input voltage-standing-wave-ratio and isolations between output ports in a given frequency band may be achieved by a finite number of cascaded sections. Determination of the characteristic impedances of the transmission line segments and the resistances of the associated isolation resistors are formulated for a given number of sections and frequency bands. Values of these quantities are tabulated for number of sections from two to four and bandwidth from f sub 2:f sub 1 = 1.5 to 10.0. The second phase of this investigation is a waveguide power divider which is capable of high power operation. A qualitative discussion shows that multifurcating an expanded E-plane waveguide may be possible for dual band operations. Experimental results are presented for a simple design of this device.
