Adjustable Power Splitter And Corresponding Methods & Apparatus

View page
US Patent:
20130194023, Aug 1, 2013
Filed:
Jan 27, 2012
Appl. No.:
13/360473
Inventors:
Abdulrhman M.S Ahmed - Gilbert AZ, US
Mario M. Bokatius - Chandler AZ, US
Paul R. Hart - Phoenix AZ, US
Joseph Staudinger - Gilbert AZ, US
Richard E. Sweeney - Chandler AZ, US
International Classification:
G06F 7/44
US Classification:
327360
Abstract:
An adjustable power splitter includes: a power divider with an input and a first and second divider output; a first adjustable phase shifter and first adjustable attenuator series coupled to the first divider output and providing a first power output; and a second adjustable phase shifter and second adjustable attenuator series coupled to the second divider output and providing a second power output.

Modifiable Signal Adjustment Devices For Power Amplifiers And Corresponding Methods & Apparatus

US Patent:
20160094187, Mar 31, 2016
Filed:
Sep 29, 2014
Appl. No.:
14/500992
Inventors:
- Austin TX, US
ABDULRHMAN M.S. AHMED - GILBERT AZ, US
PAUL R. HART - PHOENIX AZ, US
MONTE G. MILLER - PHOENIX AZ, US
NICHOLAS J. SPENCE - PHOENIX AZ, US
International Classification:
H03F 1/02
H03F 3/21
H04B 1/04
H03F 3/19
Abstract:
An embodiment of an amplifier system includes a modifiable signal adjustment device with an RF signal adjustment circuit coupled between first and second nodes. The RF signal adjustment circuit includes an adjustable phase shifter and an adjustable attenuator coupled in series with each other. The device also includes a memory and a controller circuit. The controller circuit retrieves a phase shift value and an attenuation value from the memory. The controller circuit then controls the adjustable phase shifter to apply a phase shift corresponding to the phase shift value to an input RF signal received at the first node, and controls the adjustable attenuator to apply an attenuation corresponding to the attenuation value to the input RF signal. Applying the phase shift and the attenuation results in an output RF signal at the second node.

Adaptive Adjustment Of Power Splitter

US Patent:
20150116039, Apr 30, 2015
Filed:
Oct 29, 2013
Appl. No.:
14/066601
Inventors:
Abdulrhman M.S. Ahmed - Gilbert AZ, US
Paul R. Hart - Phoenix AZ, US
Joseph Staudinger - Gilbert AZ, US
Assignee:
FREESCALE SEMICONDUCTOR, INC. - Austin TX
International Classification:
H03F 1/02
H03F 3/21
US Classification:
330295
Abstract:
A device includes a power splitter configured to couple to an amplifier having a first path and a second path. The device includes a controller coupled to first and second variable attenuators and first and second adjustable phase shifters. The controller is configured to monitor a phase shift and an output power of each of the first path and second path of the amplifier, and adjust at least one of the first and second variable attenuators and the first and second adjustable phase shifters based upon the phase shift and the output power of each of the first path and second path of the amplifier to modify an input signal to the first path or the second path of the amplifier.

Amplifier Calibration

US Patent:
20140354362, Dec 4, 2014
Filed:
Aug 20, 2014
Appl. No.:
14/464270
Inventors:
Abdulrhman M.S. Ahmed - Gilbert AZ, US
Paul R. Hart - Phoenix AZ, US
Ramanujam Shinidhi Embar - Chandler AZ, US
Assignee:
FREESCALE SEMICONDUCTOR, INC. - AUSTIN TX
International Classification:
H03F 3/21
H03F 3/19
H03F 1/02
US Classification:
330295
Abstract:
A system and method of calibrating an amplifier are presented. The amplifier has a first amplification path and a second amplification path. A first state of the amplifier is identified defining a first phase shift of the first path and a second phase shift of the second path resulting in a maximum efficiency of the amplifier when an attenuation of the first path and an attenuation of the second path are set to first attenuation values. The attenuation of the first path and the attenuation of the second path is set to achieve a maximum efficiency of the amplifier when the phase shift of the first path and the phase shift of the second path are set according to the first state.
