摘要： A constant “R” network distributed amplifier formed in a multi-layer, low temperature co fired ceramic structure comprises multiple cascaded constant “R” networks for amplifying a signal applied thereto. Each one of the multiple cascaded constant “R” networks is formed in the ceramic structure and includes a plurality of ceramic layers each of which have a top and bottom planar surfaces which, when bonded together form the ceramic structure. A transmission line is formed on the top surfaces of each of the ceramic layers having a beginning end and a distal end and has a generally rectangular shape. The distal end of the transmission line formed on a lower ceramic layer is connected to the beginning end of the transmission line formed on the next adjacent upper ceramic layer by way of vias formed in the ceramic layers through which metal conductive material is formed there through. The transmission lines and the capacitance established between the individual layers form a LC structure. An output is provided at the middle portion of the transmission line formed on the middle ceramic layer that is coupled to the drain of a FET.
