  • Transmitter-receiver that is less susceptible to interference from another transmitter-receiver
    Publication number: 20040009753
    Abstract: A transmitter-receiver comprises a transmission circuit which outputs a transmitter signal; and a reception circuit which receives a receiver signal whose frequency is different from that of the transmitter signal. The reception circuit has a mixer which first converts a frequency of the receiver signal to make it an intermediate frequency signal; and a trap circuit for attenuating the transmitter signal outputted from the transmission circuit is located before the mixer inside the reception circuit to prevent its own transmitter signal from entering the reception circuit.
