A two-way power divider has one output port terminated in a matched load, as shown below. Find the noise figure of the resulting two-port network if the divider is
(a) an equal-split two-way resistive divider,
(b) a two-way Wilkinson divider, and
(c) a 3 dB quadrature hybrid. Assume the divider in each case is matched, and at room temperature.
