Abstract
A single stage unequal power combiner is proposed. Instead of conventional combiner plus impedance transformer of 2-stage unequal combiner, the single stage combiner gets rid of the input impedance transformer. The single stage combiner supports adjustable transmission line impedance and reasonable mismatch loss, assuming the that power ratio of the input signals is within a certain range. The single stage combiner also has an adjustable isolation resistor for different power ratios. A structure of switchable branch characteristic impedance, switchable isolation resistor for the unequal combiner is proposed as the preferred embodiment. In one advantageous aspect, broader coverage angle in a single array module can be realized via an antenna diversity switch.
