Abstract
Embodiments are directed to a RF combiner/splitter having a first port separated from a second port and a third port by a generally tapering microstrip section. The second and third ports are separated by a generally rectangular bridge bar having a width selected to match the impedance of devices to be connected to the second and third ports and a length selected to provide a separation between the second and third ports of approximately quarter wavelength at a center point of an operational frequency of the devices. In a first embodiment, a horizontal RF choke joint is positioned between the first port and the tapering section. In a second embodiment, one choke joint is positioned between the second port and the bridge bar and a second choke joint is positioned between the third port and the bridge bar.
