Abstract: A mobile complex digital TV reception module is provided to receive the terrestrial and satellite digital TV broadcasting through one module. A terrestrial filter(120) passes the terrestrial TV frequency band of about 45 MHz-850MHz. A satellite filter(140) passes the satellite TV frequency band of about 950 MHz-2500MHz. An RF(Radio Frequency) member(300) converts the RF signals into a baseband signal according to a channel selection signal. A baseband member(400) processes the baseband signal from the RF member. The first input amplifying member(220) amplifies the RF signal of the terrestrial filter. The second input amplifying member(240) amplifies the RF signal of the satellite filter. A control member(500) drives the first input amplifying member when the channel selection signal is the terrestrial selection signal.
