SYSTEMS AND METHODS FOR CONTROLLING THE VOLTAGE OF SIGNALS USED TO CONTROL POWER AMPLIFIERS
摘要
<p>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.</p>
