APPARATUS FOR INTERRUPTING TRANSMITTING AND RECEIVING SIGNAL INTERFERENCE OF MOBILE TERMINAL

摘要

PURPOSE: An apparatus for interrupting transmitting and receiving signal interference of a mobile terminal is provided to interrupt the desertion of transmitting and receiving signal to a transmitting terminal or a receiving terminal. CONSTITUTION: A transmitting terminal(191) consisting the first mixer(120), the first band pass filter(130), a power amplifier(140) up converts an input signal and then amplifies the signal. A receiving terminal(190) including a low noise amplifier(160), the second band pass filter(170), the second mixer(180), and low noise-amplifies and down converts a radio signal inputted through an antenna. A duplexer(150) connects the antenna with the transmitting terminal(191) or the receiving terminal(190). A local oscillator(110) supplies the mixers(120,180) with frequency. The first interrupting part(100) is formed between the local oscillator(110) and the transmitting terminal(191) for connecting the frequency generated in the local oscillator(110) to the transmitting terminal(191) and interrupting to transmit the signal deserted in the transmitting terminal(191) to the receiving terminal(190). The second interrupting part(101) is formed between the local oscillator(110) and the receiving terminal(190) for connecting the frequency generated in the local oscillator(110) to the receiving terminal(190) and interrupting to transmit the signal deserted in the transmitting terminal(191) to the receiving terminal(190).
