A circuit that blocks the effect of the transmit frequency on the receive frequency

摘要

the design of the frequency is the frequency of the impact block in the circuit is more detailed, wireless transmitting and receiving device of a radio signal transmitting and receiving a signal of the signal of ubc1bub294 prevent the influence to the circuit. a wireless transmitting and receiving device, the receiving frequency converter, a frequency converter (3) and a transmitting part (4) connected between the transmission and the frequency converter (4) from the frequency conversion part or not (3) affected the signal in order to eliminate the a transmitting frequency to transform part (4) of the output signal with proper level decreased after the end of the above frequency conversion part (3) of the transmission of the signal to the circuit to achieve.
