A kind of variable power divider realize method: variable power divider is three port devices, i.e. input and outfan I, outfan II. Variable power divider of the present utility model make use of the principle of reflection phase shifter cleverly. Owing to variable condenser I and variable condenser II is net resistance element, when its be connected on the outfan 3 mouthfuls of electric bridge III, 4 mouthfuls time, due to the effect of net resistance, signal is all reflected back, and therefore will not be changed by the signal amplitude of electric bridge III. But, a reflected phase can be added when signal is reflected, and this reflected phase can be attached on the signal by electric bridge III, causes the signal phase by electric bridge III to change. Therefore the method that can take to regulate the capacitance of variable condenser I and variable condenser II so that additional reflected phase changes, thus causing the signal phase by electric bridge III that corresponding change occurs accordingly. When signal is inputted by variable power divider input, it is divided into two-way after electric bridge I, wherein change through the signal phase of electric bridge III, after the two paths of signals synthesis then through electric bridge II, the power of the signal of variable power divider outfan I, outfan II output will change. When continuously adjusting variable condenser I and variable condenser II, variable power divider outfan I, outfan II merit proportion by subtraction will recur change. Reasonably select the capacitance of variable condenser I and variable condenser II, will obtain it is desirable that merit proportion by subtraction.
