Abstract:
A method for controlling RF power of a paging transmitter having a matching table where the power value corresponding to power detect voltage of a radio signal transmitted from a base station and the temperature value corresponding to temperature detect voltage upon transmitting said radio signal are mapped, said paging transmitter being used at wide operation temperature range and at wideband frequencies, the method comprising the steps of:detecting said power detect voltage of said radio signal and said temperature detect voltage of said radio signal to determine the current power of a) said radio signal upon transmission;analyzing frequency and temperature characteristics of the radio signal upon transmission;determining a frequency offset value when the analyzed frequency of the radio signal upon transmission is not in an intermediate range;determining a temperature offset value when the analyzed temperature of the radio signal upon transmission is not in an intermediate range;calculating a final power value, said final power value being compensated by said frequency offset value and said temperature offset value when applicable;comparing said final power value of the radio signal with the current power; andadjusting the power of the transmitted radio signal in response to said comparison.
