ABSTRACT:
A high performance attenuator configuration divides a signal path into a plurality of parallel attenuator paths, each path having a predetermined attenuation value. A switch for each attenuator path is provided to couple selectively one of the attenuator paths to an input connector. Each attenuator path has an FET buffer amplifier, and the outputs of the FET buffer amplifiers are input to an electronic switch or multiplexer. The electronic switch selects the FET buffer amplifier output to be passed on to an output drive circuit.
