ABSTRACT:
A feedforward amplifier arranged as a unitized gain block particularly suitable for use in cable communication systems. The feedforward amplifier includes a single circuit board integrally mounting the directional couplers, delay lines and attenuator circuitry in a symmetrical arrangement. The main and error amplifiers are mounted separately from the main circuit board via releasable connectors and each amplifier is arranged on its substrate as a mirror image of the other to provide a symmetrical signal path. The amplifiers and the circuit board are enclosed within a compact metal housing which provides heat sinking for the amplifiers and facilitates removal of the amplifiers for servicing.
