Abstract
Devices, systems, and methods for amplifying full duplex signals that include a first frequency band shared between an FDX upstream signal and a downstream FDX signal, and a second frequency band having a legacy upstream signal, where the legacy upstream signal and the FDX upstream signal are amplified by a common amplifier.
Claims19
An amplifier circuit comprising:
- a northbound port and a southbound port, each propagating a full duplex signal having a first frequency band that includes both an FDX upstream signal and a downstream FDX signal, and each propagating a legacy upstream signal in a second frequency band that is free from including a downstream signal;
- and
- a power amplifier that simultaneously amplifies the FDX upstream signal and the legacy upstream signal.
A method comprising:
- receiving at an FDX amplifier circuit a full duplex downstream signal and a full duplex upstream signal that together share a first frequency band;
- receiving at the FDX amplifier a legacy upstream signal in a second frequency band that is free from including a downstream signal;
- and
- amplifying a combined signal that includes both the full duplex upstream signal and the legacy upstream signal.
