AbstractThe invention relates to the distribution of power and control commands to a plurality of pulsed T/R modules coupled to the antenna elements of a phased array radar and arranged in rows and columns. The novel power distribution system includes a large number of small capacitors, at least one per module, a lesser number of large capacitors, at least one at each end of each row, and bus bars dimensioned for a very small r.f. impedance for supplying peak power in a timely manner to the modules from the large capacitors. Each row has four large (1KW) dc power supplies for providing the average power. The power conditioning elements within the modules are of reduced bulk while achieving "droop" free operation. The control commands are carried by lower current capacity runs on a layer laminated to the bus bar.Connectors attached to the laminated bus bar and indexed at the module positions provide high power and control commands. The arrangement permits automated testing of the connections and is of high reliability.
