ABSTRACT:
A method for controlling and maintaining the power of an RF signal outputted in a paging transmitter operating at a wideband frequency range (over 10 MHz) and wide temperature range (-30.about.+60.degree. C.). The power value corresponding to the power detect voltage (PDV) of a radio signal transmitted from a base station and the temperature value corresponding to temperature detect voltage (TDV) upon transmitting the radio signal are mapped using a matching table. The method includes the steps of: (a) detecting a voltage representing the power of the radio signal upon transmission of the same, searching the matching table for a power value and temperature value for transmission of the radio signal and displaying the searched values to an operator; (b) analyzing the frequency and temperature of the transmitted radio signal and calculating final power value data of the radio signal after compensating the power value by using a first offset value having preset power error between real power and operation power according to the given frequency range of wide frequency band, and a second temperature offset value having which corrects any error between the real power and operation power according to the given temperature range of wide operation temperature band; and (c) comparing the calculated final power data with current operation power data and controlling the power of the transmitted radio signal.
