Embodiment Construction

[0021] The present invention describes a method of controlling the voltage of a signal used to control a power amplifier. The first multiplexer and the second multiplexer are set to an enable signal. The first multiplexer is on a first integrated circuit and the second multiplexer is on a second integrated circuit. A command is written to the first multiplexer to set the first multiplexer to one of a plurality of control signals for controlling a power amplifier. A command is written to the second multiplexer to select one of the plurality of control signals mapped to the first multiplexer. The second integrated circuit is connected to a power source.

[0022] The invention also describes a wireless device for controlling the voltage of a signal used to control a power amplifier. The device includes a processor and memory in electronic communication with the processor. Instructions are stored in the memory. The instructions are executable to set the first multiplexer and ...

Abstract

A method for controlling the voltage of signals used to control power amplifiers is described. A first multiplexer and a second multiplexer are set to an enabling signal. The first multiplexer is on a first integrated circuit and the second multiplexer is on a second integrated circuit. A command is written to the first multiplexer to set the first multiplexer to one of a plurality of control signals used to control a power amplifier. A command is written to the second multiplexer to select one of the plurality of control signals that maps to the first multiplexer. The second integrated circuit is connected to a power supply.

Description

[0001] priority [0002] This application is about the inventors David Maldonado (David Maldonado), Xi Peihou (Puay HoeSee), Sun Bo (Bo Sun) and Zhang Guang (Guang Zhang) filed on December 20, 2007 U.S. Provisional Patent Application No. 61 / 015,654 for "SYSTEMS AND METHODS FORCONFIGURING MULTIPLE MULTIPLEXERS VIA AN EXTERNAL INTEGRATEDCIRCUIT," and claiming priority thereto, This case is incorporated herein by reference. technical field [0003] The system and method of the present invention relate to communication and wireless related technologies. In particular, the systems and methods of the present invention relate to systems and methods of controlling the voltage of signals used to control power amplifiers. Background technique [0004] Wireless communication devices have become smaller and more powerful to meet consumer needs and to improve portability and convenience. Consumers have become dependent on wireless communication devices, such as cellular telephones, p...
