Title: Automatic setting device for band pass filter
Inventor: ISHIKAWA YOHEI
IPC: H01P7/10
Filed: 1992-01-09
Abstract: PURPOSE:To adjust the center frequency of a band pass filter to a desired setting value automatically with high accuracy. CONSTITUTION:A reference signal having a center frequency to be set to a band pass filter 30 is generated from a signal generator 71, and a local oscillator 61 generates a local oscillation signal having a local oscillating frequency deviated from the center frequency by an intermediate frequency. A signal reflected, when the above-mentioned reference signal is inputted to the filter 30, is extracted and the extracted signal is converted into an intermediate frequency signal having the intermediate frequency by using the local oscillation signal with a mixer 64 and a band pass filter 65. The converted intermediate frequency signal is detected by a detector 67 and the element constant of a frequency variable element in the filter 30 is changed to minimize the level of the detection signal, thereby controlling the center frequency of the filter 30.
