View page
US Patent:
7352237, Apr 1, 2008
Filed:
Mar 25, 2005
Appl. No.:
11/089834
Inventors:
William Martin Snelgrove - Toronto, CA
Kelly Mekechuk - Austin TX, US
David Kelly - Austin TX, US
Richard Wilson - Austin TX, US
Assignee:
Pulsewave RF, Inc. - Austin TX
International Classification:
H03F 3/38
US Classification:
330 10, 330306
Abstract:
A radio frequency power amplifier and corresponding methods are arranged and configured to drive or provide a radio frequency signal to a resonant load. The amplifier includes a radio frequency switching stage with an output that is coupled to a resonant circuit and configured to provide an output signal with amplitude modulation corresponding to amplitude modulation of an input signal when powered from a fixed voltage power supply and a feedback control system coupled to the input signal and the output signal. The feedback control system includes a sequencer configured to provide a sequencer output that is used to drive the radio frequency switching stage, where the sequencer output has an OFF state that begins at a variable time corresponding to the input and output signal.

Radio Frequency Power Amplifier And Method Using A Controlled Supply

US Patent:
7474149, Jan 6, 2009
Filed:
Jun 15, 2007
Appl. No.:
11/818925
Inventors:
William Martin Snelgrove - Toronto, CA
Kelly M. Mekechuk - Austin TX, US
Assignee:
PulseWave RF, Inc. - Austin TX
International Classification:
H03G 3/20
US Classification:
330136, 330129
Abstract:
A radio frequency power amplifier includes a feedback control system coupled to an input signal and a first feedback signal and configured to provide an output; a controlled supply configured to provide power that is controlled in accordance with a signal; and a radio frequency gain stage powered from the controlled supply, driven by the output from the feedback control system, and configured to provide an output signal at the radio frequency to a resonant load, where the first feedback signal corresponds to the output signal. Some embodiments include a sequencer in the feedback control system and others utilize an additional feedback loop to control the power provided by the controlled supply.

Switching Power Amplifier Using A Frequency Translating Delta Sigma Modulator

View page
US Patent:
20050179487, Aug 18, 2005
Filed:
Feb 17, 2004
Appl. No.:
10/780188
Inventors:
Wai Lee - Austin TX, US
Shawn Stapleton - Austin TX, US
Kelly Mekechuk - Austin TX, US
International Classification:
H03F003/38
US Classification:
330010000
Abstract:
A radio frequency (RF) switching power amplifier comprises: a switching amplifier to provide an amplified signal within an RF band; and a delta signal modulator (DSM) that is operable; to control the switching amplifier in a feedback configuration, to process an input signal within an intermediate frequency (IF) band where the input signal corresponds to a base band signal and the amplified signal, and to provide an output signal within the RF band to drive the switching amplifier. Certain embodiments allow for or compensate for a floating or variable IF band and multiple RF bands.

US Patent:
20060217086, Sep 28, 2006
Filed:
Apr 28, 2006
Appl. No.:
11/413998
Inventors:
Kelly Mekechuk - Austin TX, US
William Snelgrove - Toronto, CA
International Classification:
H01Q 11/12
H04B 1/04
US Classification:
455126000
Abstract:
A radio frequency power amplifier and corresponding methods are arranged and configured to drive a resonant load with an output signal that includes AM or complex modulation from an input signal. The amplifier includes: a radio frequency switching stage with an output that is coupled to a resonant circuit and configured to provide the output signal when powered from a fixed voltage power supply; a feedback control system, coupled to the input signal and the output signal, and further comprising a sequencer configured to provide a sequencer output that is used to drive the radio frequency switching stage; and a second feedback system responsive to the sequencer output and configured to provide a second feedback signal that is coupled to the feedback control system, where the sequencer output has an OFF state that begins at a variable time corresponding to the input signal, the output signal, and the second feedback signal.

US Patent:
20090027119, Jan 29, 2009
Filed:
Jul 25, 2008
Appl. No.:
12/220594
Inventors:
Bertrand Jeffery Williams - Austin TX, US
Kelly Mekechuk - Austin TX, US
Thomas Johnson - Austin TX, US
Dan Huslig - Dripping Springs TX, US
International Classification:
H03F 1/26
US Classification:
330149, 330136
Abstract:
A radio frequency power amplifier system includes a power amplifier coupled to an input signal and configured to provide an output signal at a radio frequency; a signal cancellation system coupled to the input signal, and a first feedback signal, which is based on the output signal, and configured to provide an error signal with a reduced level of the input signal; and a feedback control system coupled to the error signal and configured to provide a correction signal that is used to reduce distortion in the output signal. A corresponding method includes amplifying in a forward path an input signal to provide an output signal at a radio frequency; combining a reference and a first feedback signal to provide an error signal with a reduced level of the input signal; providing, responsive to the error signal and in a. feedback control system that is separate from the forward path, a correction signal; and then using the correction signal to reduce distortion in the output signal.

Scalable Periphery Tunable Matching Power Amplifier

US Patent:
20220329215, Oct 13, 2022
Filed:
Apr 27, 2022
Appl. No.:
17/731048
Inventors:
- San Diego CA, US
David Halchin - Summerfield NC, US
Jeffrey A. Dykstra - Woodstock IL, US
Michael P. Gaynor - Crystal Lake IL, US
David Kovac - Arlington Heights IL, US
Kelly Michael Mekechuk - Austin TX, US
Gary Frederick Kaatz - Barrington IL, US
Chris Olson - Palatine IL, US
International Classification:
H03F 1/56
H03F 3/21
H03F 3/217
H03F 1/02
H03F 1/22
H03F 3/195
H03F 3/24
H03F 3/72
H03F 3/193
Abstract:
A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.
