The invention provides an S-band single-point frequency micro-packaging phase-locked source and electronic equipment, and relates to the technical field of phase-locked sources. The phase-locked loop comprises a phase-locked loop and an amplifying and filtering link, the amplifying and filtering link comprises a low-noise amplifier and an FBAR band-pass filter chip; the low noise amplifier is used for amplifying a signal generated by the loop, and the FBAR band-pass filter chip is used for filtering the amplified signal; and the phase-locked loop and the amplifying and filtering link are packaged in a micro-packaging box body. The FBAR is adopted at the signal output end to filter stray, the advantages of reducing frequency mutual interference and improving the stray suppression degree are achieved, meanwhile, an FBAR band-pass filter chip is adopted, miniaturization design is adopted, a phase-locked loop and an amplification filtering link are packaged in the same micro-packaging box, a micro-packaging struc
