Switchable power level detector for multi-mode communication device

A method for adjusting power level when switching between bands in a multiband wireless communication device comprising:

• monitoring for a change in mode of operation from a first mode to a second mode;
• responsive to detecting a change in mode of operation, generating and sending a switch control signal to a switch;
• responsive to the switch control signal, selectively changing a detector configuration from operation in a first detector mode to operation in a second detector mode wherein selectively changing a detector configuration comprises switching a sampler configured for operation in the second mode to be connected to the detector;
• detecting one or more aspects of an outgoing signal;
• and
• responsive to detecting one or more aspects of an outgoing signal, generating an amplifier control signal to thereby control the power level of the outgoing signal.

A system for controlling transmit power level in a multi-mode wireless communication device comprising;

• an amplifier configured to receive an outgoing signal and generate an amplified outgoing signal responsive to an amplifier control signal;
• a detector, configured to sample the amplified outgoing signal and generate a feedback signal corresponding to the power level of the amplified outgoing signal, wherein the detector is further configured with a switchable selector to configure operation of the detector to match a mode of operation wherein the switchable selector to comprises a multiband switch having three inputs and a single output;
• and
• a controller configured to process the feedback signal to generate the amplifier control signal.
