Abstract: PURPOSE: A digital multimedia broadcast receiver suitable for a mobile device is provided to make a mobile device compact and slim by employing a small IC(Integrated Circuit) and a chip and by implementing an input/output connector and an antenna connector as a printed pattern. CONSTITUTION: An antenna connector(ANT-CONT) is formed as a printed pattern to be connected to an antenna(ANT). An RF(Radio Frequency) unit(31) includes a flip chip type RF IC for selecting a digital multimedia broadcast signal among signals received through the antenna connector(ANT-CONT) and converting it into an IF signal. A baseband unit(32) includes an ADC(Analog-to-Digital Converter) IC for converting the IF signal inputted from the RF unit(31) into a digital signal, a flip chip type CPLD(Complex Programmable Logic Device) IC for converting a parallel signal outputted from the ADC IC into a serial signal, and a flip chip type DSP(Digital Signal Processor) IC for demodulating an output signal of the CPLD IC. An interface unit(33) converts the demodulated signal into a signal suitable to be processed in a mobile device(40) and then provides it to the mobile device(40). An input/output connector(IO-CONT) is formed as a printed pattern to connect the interface unit(33) and the mobile device(40).
