An apparatus, system, and method for affordably distributing cable communication signals at greatly reduced power consumption levels with high signal quality with an active tap having gain stage characterized by low power (less than 1 Watt), low noise figure (less than 3 dB), high bandwidth (typically DC-2 GHz), and high gain (at least 15 dBmV).

In a transfer linearization (TL) circuit one or more biased nonlinear elements form a nonlinear attenuator and a biased network to allow adjustment of diodes to linearize the overall transfer of the TL circuit and an amplifier being linearized. The transfer linearization circuit reduces distortion encountered in a broadband RF amplifier. The circuit compensates for attenuation of amplified broadband signals in CATV systems. The transfer linearization circuit provides low insertion loss and requires very low power consumption. Nearly constant impedance and constant insertion loss is provided across a wide frequency range and reduces both in-band and out-of-band third order distortions. The TL circuit exhibits instantaneous amplitude and phase transfer correction. No tuned frequency selective components are required so that adjustments are relatively straightforward.
