PURPOSE: A multi-channel digital broadcasting transmission and reception apparatus and method thereof are provided to reduce inference on a communication system and other broadcasting systems by using a frequency conversion method. CONSTITUTION: A frequency conversion module(210) converts TV signals into other frequencies by using a first control signal of a control unit. A synthesizer(220) combines signals outputted from the frequency conversion module in a path. An HPA(High Power Amplifier)(230) amplifies a predetermined gain by using the first control signal outputted from the synthesizer. A BPF(Band Pass Filter)(240) passes a predetermined frequency band of a signal received from the HPA. An MCU(Micro Control Unit)(250) controls the frequency conversion module and the HPA. |
