1. A radio transmitter system, comprising:
- an RF power amplifier comprising at least one RF power transistor;
a control processor that generates at least one control signal responsive to a user input; and
at least one circuit configured for selectively varying at least one operating characteristic of said RF power amplifier responsive to said at least one control signal, said operating characteristic selectively varied so as to increase a power output of said radio transmitter system based on at least one user input command;
wherein said control processor is programmed to automatically generate said control signal in response to said at least one user input command that indicates that a second transmission mode has been selected, said second transmission mode being a burst mode in which said radio transmitter system transmits bursts of data at a second duty cycle lower than a first duty cycle associated with a first transmission mode defined with respect to a current state of said radio transmitter system; and
wherein a first RF power output in said first transmission mode comprises substantially a maximum available RF output power of said transmitter in at least said first transmission mode exclusive of potential damage to said transmitter, and a second RF power output in said second transmission mode comprises a power level greater than said first RF power output level, exclusive of damage to said transmitter.

Abstract
Transmitter (116) designed to automatically reconfigure one or more circuit parameters associated with an RF power amplifier (210) in response to certain user input commands. Specifically, a transmitter circuit configuration is automatically modified under certain conditions to produce a higher RF output power. The higher RF power output is possible because the transmitter configuration is adjusted specifically for use under a particular set of operating conditions. The operating conditions that trigger the higher powered configuration include burst transmission mode.

23. A method for obtaining maximum output power from a transmitter, comprising:
-
operating a radio transmitter at a first RF output power level in a first transmission mode, said first RF output power level comprising substantially a maximum available RF output power of said transmitter in at least said first transmission mode exclusive of potential damage to said transmitter; responsive to a user command, operating said radio transmitter in a second transmission mode different from said first mode; automatically increasing an RF output power of said transmitter to a second RF output power level greater than said first RF output power level, exclusive of damage to said transmitter, when said second transmission mode is selected; wherein said second transmission mode comprises a burst mode in which said radio transmitter system exclusively transmits packet data in bursts at a second duty cycle lower than a first duty cycle associated with a first transmission mode. - View Dependent Claims (24)

25. A communication system in which maximum output power is obtained from a transmitter in a plurality of operating modes, comprising:
-
a radio transmitter configured to operate at a first RF output power level in a first transmission mode, said first RF output power level comprising substantially a maximum available RF output power of said transmitter in at least said first transmission mode exclusive of potential damage to said transmitter; processing means responsive to a user command, configured for causing said radio transmitter to operate in a second transmission mode different from said first mode, said processing means configured for automatically increasing an RF output power of said transmitter to a second RF output power level greater than said first RF output power level when said second transmission mode is selected, without causing damage to said transmitter; wherein said second transmission mode is a burst mode in which said radio transmitter system exclusively transmits packet data in bursts at a second duty cycle lower than a first duty cycle associated with a first transmission mode.
