The characteristic and work principles of a PLL frequency synthesizer MC145152-2 were mainly introduced. Based on the chip, designing of the synthesizer work at 1800MHz was developed followed with a theoretic discussion of the circuit from the selection of the components and analysis of the parameters to the assembly and debugging of the hardware. Tests proved that the lower phase noise and higher frequency stability was achieved when comparing with a traditional loop.
