Patent ID: 8872984

Claim:
A tuner module which transmits/receives a signal for mobile communication through a transmitting/receiving antenna, and receives a signal of a digital television broadcast through a reception antenna or the reception antenna and the transmitting/receiving antenna, the module comprising: a first high frequency switch which has a first contact point to which a transmitting/receiving RF signal for the mobile communication is supplied, a second contact point to which a reception RF signal of the digital television broadcast is supplied, and a common contact point to which one of the first contact point and the second contact point is selectively connected and which is connected to a first transmitting/receiving antenna; a second high frequency switch which has a first contact point to which a transmitting/receiving RF signal for the mobile communication is supplied, a second contact point to which a reception RF signal of the digital television broadcast is supplied, and a common contact point to which one of the first contact point and the second contact point is selectively connected and which is connected to a second transmitting/receiving antenna; a first digital broadcast RF reception unit which receives a reception RF signal of the digital television broadcast supplied from the second contact point in the first high frequency switch, and converts the reception RF signal into a reception IF signal; a second digital broadcast RF reception unit which receives a reception RF signal of the digital television broadcast supplied from the second contact point in the second high frequency switch, and converts the reception RF signal into a reception IF signal; a third digital broadcast RF reception unit which receives a reception RF signal of the digital television broadcast supplied from a first reception antenna, and converts the reception RF signal into a reception IF signal; a fourth digital broadcast RF reception unit which receives a reception RF signal of the digital television broadcast supplied from a second reception antenna, and converts the reception RF signal into a reception IF signal; and a digital broadcast demodulating unit which receives the reception IF signals obtained by conversion by any of the first to fourth digital broadcast RF reception units, performs diversity combining on the signals, demodulates and externally outputs the signals.
