RF OUTPUT MONITOR TRANSMITTER AND RF OUTPUT MONITORING METHOD

摘要

PURPOSE: An RF(Radio Frequency) output monitor transmitter and an RF output monitoring method are provided to prevent an error operation of the transmitter by previously monitoring whether an interference frequency exists in circumference and operating the transmitter after the intereference frequency disappears. CONSTITUTION: An operation unit(1) informs the operation state of a user. A monitoring unit(3) varies a voltage level according to an interference frequency within an operation distance. A control unit(2) detects a voltage level of the monitoring unit(3) for judging whether the interference frequency exists within the operation distance according to the signal provided from the operation unit(1). If the detected voltage level is greater than a reference value, an LED(Light-Emitting Diode) display unit(4) and an LCD(5) inform that the interference frequency exists from the control unit(2). If the detected voltage level is greater than the reference value, a voice generating unit(6) generates a warning sound for informing that the interference frequency exists from the control unit(2). An RF amplifying unit(7) amplifies a corresponding frequency, and outputs the amplified signal for providing a corresponding operation signal according to the operation of the user when the interference frequency disappears.
