REPEATER OF PULSE MODULATING WAVE

摘要

PURPOSE:To minimize a carrier frequency deviation between burst signals of an output signal as less as possible by converting plural burst pulse modulating wave input signals into the output signal by a timewise synthesis circuit after converting the said input signals into an identical intermediate frequency signal. CONSTITUTION:An output of a high frequency oscillator 21 being a reference is demultiplexed partly as the 1st local oscillation output FL1 and the remaining signal drives the 1st frequency converter 24. On the other hand, an output of a low frequency oscillator 23 is impressed also thereto and the upper side band is extracted as an output. A part of this output is extracted from a branching circuit 25 and becomes an output of the 2nd local oscillator. The remaining output drives the 2nd frequency converter 28. Further, the remaining output of the low frequency oscillator output is impressed to the 2nd frequency converter 28 after being amplified. The local oscillator outputs shifted by a frequency delta are obtained sequentially in this way.
