Reconfigurable Unequal Power Divider With a High Dividing Ratio

This letter introduces a novel simple structure for the realization of a reconfigurable unequal power divider with a high dividing ratio. Two transmission modes, high power mode and low power mode, can be obtained by this reconfigurable unequal power divider. Only three p-i-n diodes are required without dc blocking capacitors. In addition, the parameters of p-i-n diodes under different bias conditions are involved in matching. For verification, measured results of a reconfigurable 1:5 power divider operated at 5 GHz are given in both transmission modes.
