Frequency Synthesizer PE3236 is a monolithic frequency synthesizer from Peregrine Corporation. In this paper, the characteristics of PE3236 are briefly introduced, and the method of designing the frequency synthesizer using PE3236 is described in combination with the practical engineering application. A L-band PLL frequency synthesizer is realized. By analyzing the characteristics of PE3236 and frequency synthesizer and using the main devices such as loop filter and voltage-controlled oscillator, the design of PLL frequency synthesis circuit is completed. The test results show that the loop of the frequency synthesizer is stable, and the frequency can be changed according to the requirement, which shows that the frequency stability of the output signal of the PLL synthesizer is high.
