ABSTRACT:
A variable attenuation device is provided for an antenna amplifier by providing high attenuation and low attenuation signal flowpaths connected to the amplifier input by respective pin diodes. The biasing of the diodes and, thus, the attenuation factor provided, is controlled in proportion to the output of a rectifying circuit which, in turn, provides a DC output proportional to the magnitude of a given polarity of the AC signal supplied to the amplifier from inside the subscriber's home.
