摘要: A selective call receiver (100) includes a radio frequency amplifier (202) having an output power level that is controllable. sensor (500) generates signal in response to input received at the (202). The conditioned by filter (401, 402) generate control representing effective value of then coupled adjustment circuit (403) operates adjust gain unconditionally stable feed-forward manner such remains substantially constant when sensed reaches or exceeds predetermined overload level.
