DESIGN AND IMPLEMENTATION OF PLL FREQUENCY SYNTHESIZER USING PE3336 IC FOR IRS APPLICATIONS

The design and experimental verification of a low phase noise phase locked loop (PLL) frequency synthesizer using Peregrine’s PE83336 IC is presented. This PLL is used as frequency synthesizer which generates stable and low phase noise signal for space applications. A stable reference frequency of 22.8MHz is provided to the PLL through a temperature compensated crystal oscillator (TCXO). Experimental results of the PLL frequency synthesizer shows the excellent performance achieved at X-band. The PLL model implemented with frequency resolution of 5.8MHz, and phase noise better than-81dBc/Hz @ 1 kHz offset at X-band. The complete model is fabricated on RT-duroid 6010 substrate
