TABLE OF CONTENTS A quadrature hybrid takes an input signal and divides it into two equal outputs that are 90 apart in phase, which is fine for some applications. But what if you do not want a phase shift between your output ports and you need to divide the input signal into three or four outputs? If that is the case, you can employ a simple 0 power divider that is not limited to just two outputs. Wilkensen power dividers provide a variety of output ports that are all in phase, within a reasonable tolerance. Figure 4.16 shows a two-way, a three-way, and a four-way power divider.
You can see from the figure that each of these dividers has an input port on the left that comes to a point where the device splits off and goes in as many directions as is necessary for the individual component. It should be pointed out here that the input transmission line and the output lines will be 50- ? lines. The transmission lines for the division lines will be various values, depending on the number of outputs needed. For a two-way divider, the impedance of the transmission lines going to the 50- ? outputs is 70.7 ?. You can see the difference in widths of these lines as you look inside a circuit and see the lines that make up a power divider. Also, each divider has a resistor between output ports. The resistors...
