Hi,
I understand how an equal split Wilkinson power divider works in supplying equal phase and amplitude of signals to the antenna elements of a phased array.
But what happens when the phased array is used as a receiver? The received signals are phase shifted and then combined. So the power combiner has phase shifted inputs and how then does the power combiner work?
Some may say that the phase shifted inputs result in reflections which is taken care of the resistor providing isolation between the output ports. But what when my design is without a resistor between the output ports?
