Signal amplifiers that switch to an attenuated or alternate communications path in response to a power interruption

摘要

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.

主权项

1. A bi-directional RF signal amplifier, comprising
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 diplexer having a common port, a high frequency port and a low frequency port, wherein the first output of the switching device is coupled to the common port; and an attenuator that has an attenuator input that is coupled to the second output of the switching device and an attenuator output that is directly connected to a node within the internal circuitry of the diplexer.
