Summary: | The invention discloses a single-loop frequency-division ultra-wideband phase-locked frequency synthesizer. The single-loop frequency-division ultra-wideband phase-locked frequency synthesizer comprises a crystal oscillator, a phase-locked chip, a loop filter, a voltage-controlled oscillator, a wideband one-to-two power divider, a wideband variable frequency divider and a wideband switch filter, wherein an output end of the crystal oscillator is connected with an input end of the phase-locked chip; an output end of the phase-locked chip is connected with an input end of the loop filter; an output end of the loop filter is connected with an input end of the voltage-controlled oscillator; an output end of the voltage-controlled oscillator is connected with the wideband one-to-two power divider; the wideband one-to-two power divider outputs two paths of signals; one path of signal is connected with the phase-locked chip; the other path of signal is connected with the wideband variable frequency divider; the wide |
