  • One GHZ CATV repeater station
    Patent number: 5130664
    Abstract: An apparatus for and a method of RF amplification of signals up to 1 GHz. The apparatus, known as a repeater station, is for use in Community Antenna TeleVision transmission (CATV). The RF amplification (gain) stage includes two multitransistor distributed amplifier stages connected in a push-pull configuration. Each distributed amplifier includes four transistors connected to produce two-each cascode circuits. The distributed amplifier stages are operated in push-pull configuration by means of a 180.degree. phase shifting power splitter. The push-pull configuration of the distributed amplifier operates in combination with the 180.degree. phase shifting power splitter to cancel the 2IM distortion created within the distributed amplifiers, and to double the output capability of a single distributed amplifier.
