Abstract

PURPOSE:To make easy the phase synthesis, by comparison and detection of phase difference of two reception signals, phase correction of either of two signals with endless variable phase shifter EVPS, and equalizing of the phase of the both signals. CONSTITUTION:The relative phase difference between the reception signals fed to the input terminals 1 and 2 is detected at the phase detector 23 to control EVPS 22. EVPS22 converts the detected voltage from the detector 23 to the frequency in proportion to the input voltage, it is read in the counter to operate the shift register and to control the phase delay amount between the input and output, and it equalizes the signal phase fed to the signal synthesizer 5 from the frequency mixer 4 to the signal phase fed from the frequency mixer 14. Further, the absolute phase variation of signal fed to the terminals 1 and 2 feeds back a part of the output of the synthesizer 5 to the phase difference detector PSD 26, it is compared with the phase of signal from the reference signal oscillator 9 to perform phase difference detection and to operate the voltage controlled oscillator 27, and phase compensation is made through the frequency mixers 8 and 18.
