Abstract
A dual quadrature branchline in-phase power combiner and power splitter provides a low cost and symmetrical structure for combining power from two signal ports (20, 30, FIG. 1) to an output signal port (10). When used as a power splitter, the structure accepts power from a signal port and divides the power equally and in-phase between the output signal ports (20, 30). The structure can be fabricated using microstrip, stripline, or similar technology such as suspended stripline. The structure is well matched over a large bandwidth and provides high isolation between the splitter output signal ports (20, 30).
