The PLL circuit shown in Figure 1 uses a 13 GHz Fractional-N synthesizer, wideband active loop filter and VCO, and has a phase settling time of less than 5 μs to within 5° for a 200 MHz frequency jump ...

The tasks performed by filters in various RF architectures. Differentiating factors between those architectures. Current trends in filter performance considerations. At any given time, a multitude of ...
