Scanning Receiver For Use In Power Amplifier Linearization
Scanning Receiver For Use In Power Amplifier Linearization
US Patent:
2002014, Oct 10, 2002
Filed:
Mar 5, 2002
Appl. No.:
10/090977
Inventors:
Thomas Bachman - Darlington MD, US
Robert Kooker - Freeland MD, US
Paul White - York PA, US
Paul Everline - Wildwood IL, US
Robert Snyder - New Freedom PA, US

International Classification:
H04B001/10
US Classification:
455/302000, 455/296000
Abstract:
A feed forward power amplifier system and method identify active channels across a frequency band to suppress unwanted intermodulation distortion (IMD) products in a communications signal such as a single- or multi-carrier communications signal. A scanning receiver identifies at least one active channel in a frequency band, and identifies at least one portion of the frequency band likely to include IMD products based upon the identified active channel(s). Based upon the identified portion of the frequency band, IMD products are suppressed from the communications signal, e.g., by controlling the magnitude and/or phase of a suppression signal mixed with the communications signal.
