摘要：PURPOSE: A digital radio board apparatus of a mobile communication system for processing radio data is provided, which accommodates all of 1X modem and 3X modem together. CONSTITUTION: According to the digital radio board apparatus of a mobile communication system for processing radio data, a signal modulation/demodulation unit modulates and demodulates an input/output signal. A digital signal conversion unit(120) receives a digital signal from the signal modulation/demodulation unit and converts it, and transfers it back to the signal modulation/demodulation unit. A signal control unit controls data format and rate between the signal modulation/demodulation unit and the digital signal conversion unit. A signal conversion unit(140) converts the digital signal from the digital signal conversion unit into an analog signal, and converts the inputted analog signal into a digital signal and then transfers it to the above digital signal conversion unit. An analog signal conversion unit(170) converts the analog signal from the signal conversion unit, and converts the inputted analog signal and then transfers it to the signal conversion unit again. And a signal amplification and filtering unit(150) amplifies and filters the analog signal from the analog signal conversion unit.
