Abstract
A self-tuning, resonant cavity transmitter combiner joins multiple RF transmitters and combines their signals onto a single transmission line. An additional tuning element is added to the junction of the signal paths to overcome the bandwidth limitations of the transmission lines joining the signal paths. An algorithm was developed to optimize the RF performance of the combiner by sampling the RF signals at various points in the RF circuit.

A self-tuning transmitter combiner, the combiner comprising:
- (a) a junction for combining a plurality of signals transmitted along a plurality of signal paths comprising a plurality of filters, respectively, the junction comprising a reactive element;
- and
- (b) a computer-implemented controller operable to tune the plurality of filters in accordance with a plurality of carrier frequencies of the plurality of signals, respectively, the controller being further operable to tune the reactive element such that a lowest insertion gain selected by the controller from a plurality of insertion gains respectively associated with the plurality of signal paths is maximized.
A method of tuning a combiner, the method comprising:
- (a) by a computer-implemented controller, tuning a plurality of filters of a plurality of signal paths in accordance with a plurality of carrier frequencies of a plurality of signals being transmitted along the plurality of signal paths, respectively;
- and
- (b) by the computer-implemented controller, tuning a reactive element of a junction for combining the plurality of signals, such that a lowest insertion gain selected from a plurality of insertion gains respectively associated with the plurality of signal paths is maximized.
A self-tuning transmitter combiner, the combiner comprising:
- (a) means for tuning a plurality of filters of a plurality of signal paths in accordance with a plurality of carrier frequencies of a plurality of signals being transmitted along the plurality of signal paths, respectively;
- and
- (b) means for tuning a reactive element of a junction for combining the plurality of signals, such that a lowest insertion gain selected from a plurality of insertion gains respectively associated with the plurality of signal paths is maximized.
