Miniaturized broadband small-step frequency hopping phase-locked source

The utility model relates to a miniaturized broadband small-step frequency hopping phase-locked source, which comprises a main ring and an auxiliary ring, the auxiliary ring comprises a first phase-locked loop, a first loop filter and a first voltage-controlled oscillator which are connected in sequence, and the main ring comprises a second phase-locked loop, a second loop filter, a second voltage-controlled oscillator, a mixer, an amplifier a, an amplifier b and a low-pass filter. The second phase-locked loop, the second loop filter and the second voltage-controlled oscillator are sequentially connected, the input end of the low-pass filter is connected with the mixer, the output end of the low-pass filter is connected with the input end of the amplifier a, the output end of the amplifier a is connected with the second phase-locked loop, and the auxiliary end of the second voltage-controlled oscillator is connected with the mixer through the amplifier b. The output end of the first voltage-controlled oscilla
