Abstract: An improved apparatus for delivering energy to two field applicators includes a power divider electrically coupled to a planar transmission line connecting the two field applicators. The power divider receives an input microwave signal and delivers a first power signal to an applicator along a first leg of the line, and delivers a second power signal to the other applicator along a second leg of the line. The power divider is coupled to the transmission line at a point which is remote from the applicators such that the power signals will encounter substantially identical discontinuities as the signals are coupled into their respective applicators.
