摘要： PURPOSE: A power control signal generator and a method thereof are provided so that a precise power control function can be embodied at a low price by controlling open/close loop power by converting a non-linear property of a radio frequency circuit into a linear region. CONSTITUTION: A received signal strength indication detecting unit(211) receives an external received signal strength indication signal, removes a fading ripple therefrom, converts a non-linear property into a linear property, and outputs a resulting signal to a control signal synthesizing unit(218). In addition, the control signal synthesizing unit(218) receives an external initial power setup value and closed loop power increase/decrease command, also receives the received signal strength indication signal from the received signal strength indication detecting unit(211), and outputs a power control signal to a transmission output correcting unit(213). The transmission output correcting unit(213) receives the power control signal from the control signal synthesizing unit(212) and also receives an external transmission output detecting value. When the power control signal is over a predetermined value, the transmission output correcting unit(213) monitors a transmission output level, corrects the power control signal according to an error between the power control signal value and the transmission output signal value, and externally outputs the resultant power control signal.

摘要： PURPOSE: A device and a method for controlling a reference frequency of a transceiver are provided to generated the reference frequency stably by using a frequency control quantity through an extraction of a deviation of a receive frequency. CONSTITUTION: When the first frequency error discriminating part discriminates that a frequency error detection value is smaller than the first reference value, the frequency error discriminating part maintains a reference frequency control value to f0(405). Next, the second frequency error discriminating part compares the frequency error detection value with the second reference value, and maintains a reference frequency control value of the second duty control part to Q2(fn-f0), and holds a gain coefficient(K) fixedly(407). On the contrary, when the first frequency error discriminating part discriminates that a frequency error detection value is bigger than the first reference value, a frequency error convergence discriminating part discriminates whether the frequency error detection value converges or not(408). If the frequency error detection value converges, the first frequency error discriminating part maintains the reference frequency control value of the second duty control part to Q2(fn-f0), and controls the gain coefficient to K/2(409).
