CoreHW mmWave PLL IP

CoreHW mmWave PLL comprise a high accuracy fractional N PLL frequency synthesiser with low noise VCO capable to synthesise low phase noise carrier for demanding wireless communication systems and fast chirp FMCW waveforms for various radar systems.

The PLL fundamentally operates at 19.00-20.15 GHz and a frequency multiplier converts the waveform to radar frequency band at 38-40.5 GHz and 76-81 GHz. The design is scalable and PLL IP can be customized to various mm-wave wireless communication frequency ranges.
