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.
Claims20
A bi-directional RF signal amplifier, comprising:
- an RF input port;
- a power divider network having a plurality of active RF output ports;
- an active communications path connecting said RF input port to said power divider network, said active communications path including a power amplifier to amplify a downstream signal passing along said active communications path;
- a passive RF output port;
- a passive communications path connecting said RF input port to said passive RF output port, wherein said passive communications path has no power amplifier;
- and
- a switching device having an input that is coupled to said RF input port, a first output and a second output, wherein said first output is part of said active communications path and said second output is part of said passive communications path.
A bi-directional RF signal amplifier, comprising:
- an RF input port;
- a power divider network having a plurality of active RF output ports;
- an active communications path connecting said RF input port to said power divider network, said active communications path including a power amplifier to amplify a downstream signal passing along said active communications path;
- a passive RF output port;
- a passive communications path connecting said RF input port to said passive RF output port, wherein said passive communications path has no power amplifier;
- and
- a switching device having an input that is coupled to said RF input port, a first output and a second output, wherein said first output is part of said active communications path and said second output is connected to a node within said power divider network and bypasses said at least one power amplifier.
A bi-directional RF signal amplifier, comprising:
- an RF input port;
- a power divider network having a plurality of RF output ports;
- an active communications path connecting said RF input port to said power divider network, said active communications path including a power amplifier to amplify a downstream signal passing along said active communications path;
- at least one of said plurality of RF output ports having a potential to function as either an active RF output port or a passive RF output port;
- a passive communications path connecting said RF input port to said at least one of said plurality of RF output ports, wherein said passive communications path has no power amplifier;
- and
- a switching device having an input that is coupled to said RF input port, a first output and a second output, wherein said first output is part of said active communications path and said second output is part of said passive communications path.
