ABSTRACT:
A radio frequency (RF) receiver utilizing dynamic power management for administration of power consumption. The RF receiver includes an RF antenna, an RF full band filter, an RF amplifier, an RF sub-band filter, a first local oscillator, an RF mixer, a first IF amplifier, an IF wide band filter, a second local oscillator, an IF mixer, two secondary IF amplifiers, an IF narrow band filter, a digital signal processing subsystem, three power sensors, and a control logic subsystem. Based on its location in the system, each power sensor has a unique threshold setting that is set just below a total RF power level where desired signal degradation might occur. The control logic subsystem utilizes outputs of the power sensors to detect a total RF power present due to interfering signals plus a desired signal within an entire bandwidth present at each stage and dynamically manages power by adjusting bias of each stage accordingly via its bias control outputs.
