Abstract
A selective call receiver (100) includes a radio frequency amplifier (202) having an output power level that is controllable in an unconditionally stable manner. The selective call receiver (100) includes a loading diode (403) coupled to an output of the radio frequency amplifier (202) and a feed-forward load control (201) coupled to an input of the radio frequency amplifier (202). The feed-forward load control (201) detects an input signal strength and regulates conduction of a current through the loading diode (403). In response to the input signal strength substantially reaching or exceeding a predetermined activation threshold corresponding with a predetermined input signal strength and a maximum output power level, the feed-forward load control (201) adjusts the current causing an impedance of the loading diode (403) to vary in a manner that causes the output power level to remain substantially constant.
