1. Apparatus for phase coherently combining a plurality of radio frequency (RF) signals, each RF signal exhibiting dissimilar first predetermined time delays, said apparatus comprising:

  • time delay means adapted to receive and provide a second predetermined time delay to each RF signal, the second predetermined time delay compensating for the first predetermined time delay of each RF signal, said time delay means comprising a circuit panel having located thereon a series of metallized strips, each strip of predetermined dimension and adapted for receiving a selected one of said RF signals at an input portion, said strips providing said predetermined time delay to said signal and outputting said time delayed signals at an output portion;

    combining means for combining the signals from the time delay means to provide a combined signal, said combining means introducing a predetermined timing distortion to at least some of the signals from the time delay means; and

    coupling means for coupling the RF signals to said time delay means, the coupling means including means for predeterminedly time delaying the RF signals to compensate for the corresponding timing distortion introduced by the combining means.
