1. A bi-directional RF signal amplifier, comprising:
- an RF input port;
a first RF output port;
a second RF output port;
an amplified communications path that connects the RF input port to the first RF output port;
a non-amplified communications path that connects the RF input port to the second RF output port;
a first switching device that is part of both the amplified communications path and the non-amplified communication path; and
a second switching device that is part of the non-amplified communications path;
wherein the bi-directional RF signal amplifier is configured to simultaneously carry signals on both the amplified communications path and the non-amplified communications path when power is supplied to the RF signal amplifier.

Abstract
RF signal amplifiers are provided that include an RF input port, a switching device having an input that is coupled to the RF input port, a first output and a second output, a first diplexer having an input that is coupled to both the first output of the switching device and the second output of the switching device, and a first RF output port that is coupled to an output of the first diplexer. These amplifiers further include an attenuator that is coupled between the second output of the switching device and the input of the first diplexer.
