Title: High-frequency detection circuit
Inventor: UCHIDA HIKARI
IPC: H04B17/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To control the output of a rectifier diode for detection at a high speed even when electric power abruptly increases at the time of detecting very small electric power by detecting the output of the diode in a peak-holding state. SOLUTION: Input high-frequency electric power is passed through an attenuator 2 and the attenuated power is rectified and detected by means of a rectifier diode 3 for detection. The peak of the detected output is held by the use of a peak-hold detection circuit 4 diode 3 and an amplifier 5 obtains a difference output to a reference value. A control circuit 6 always maintains the detection output of the diode 3 at a fixed value by adjusting the attenuating amount of the attenuator 2 based on the difference output of the amplifier 5. The input high-frequency power of the diode 3 has a pulse waveform and operates the circuit 6 and attenuator 2 with the pulse. Since the detection circuit 4 is used, in addition, voltage detection becomes possible in accordance with the conducting time with the pulse.  When the conducting time with the pulse is appropriately set, therefore, the allowable input power of the diode 3 can be increased and the detecting power range of the diode 3 can be widened.
