A complex digital tuner module is provided to enable a terminal circuit configured by a capacitor and a full-down resistance between the output terminals of tuner units and the ground to ground the reflected wave of an IF signal generated in the output terminals of the tuner units in the operation of the tuner, thereby preventing signal interference caused by the reflected wave, cutting and separating a flow of a DC voltage to improve reception capability. A complex digital tuner module comprises plural digital tuner modules(21,22) and a termination circuit(23). The plural digital tuner modules are comprised of tuner units(211,221) and demodulation units(212,222). The tuner units have interference between each other due to radiation generated by the storing field intensity of at least one of signals generated from each of IF(Intermediate Frequency) output pins. The termination circuit is connected between the output terminals of the tuner units and the ground to prevent mutual interference in the output terminals of the tuner units and cut an DC(Direct Current) flow and separate the DC flow from the outputted signals.
