Abstract
PURPOSE:To obtain sufficient attenuation and to remarkably improve the time delay, by lowering the frequency multiplying efficiency through forward bias current to a diode. CONSTITUTION:When no output is present at a detector of out of synchronism, a terminal 28 is grounded, a varactor (generally, frequency multiplying diode) is short-circuited with a resistor 24 and it is placed to bias state excellent in the frequency multiplying efficiency, and the signal in frequency nfs input from a terminal 21 is multiplied to the signal in mnfs and output to a tuning circuit 23. When an output is present at the detector for out of synchronism, a voltage flowing forward bias current to the varactor 22 is connected to a terminal 28 to remarkably lower the frequency multiplying efficiency of the varactor 22 and to remove the output.
