ABSTRACT:
This invention allows the combination of any M of N signal inputs, combines the signals inputs in phase, and does not require switches to terminate unused inputs.
Microstrip switching means provide an array of N quarter-wave tuners and an associated single, common, quarter-wave tuner that are interconnected by N semiconductor switching means. Each of the N semiconductor switches is connected with one of the N quarter-wave tuners and is operable to provide a low impedance between its connected quarter-wave tuner and the single common quarter-wave tuner.
Microstrip connecting means for the microstrip switching means forms an array of N transmission lines N associated quarter-wave transformers for semiconductor switch biasing and a single transmission line. Each of the N transmission lines and its associated one of the N bias quarter-wave transformers are connected together at one end and further connected with one of the N quarter-wave transformers of the microstrip switching means and has an RF connection at its other end. The single transmission line is connected at one end with the single common integral quarter-wave transformer of the microstrip switching means and has an RF connection at its other end.
Electrical current through any M of the N bias quarter-wave tuners and the connected M quarter-wave and semiconductor switches can be used to electrically connect the M quarter-wave tuners with the single common quarter-wave tuner, permitting signals on the M quarter-wave tuners to be combined in phase of the common quarter-wave tuner output.
