The mmWave PLL by CoreHW is a sophisticated frequency synthesizer designed to meet the demands of modern wireless communication networks and radar systems. It features a high-accuracy fractional-N PLL frequency synthesizer with a very low noise voltage-controlled oscillator (VCO). This design supports efficient generation of low phase noise carriers and rapid chirp frequency modulations required for fast-frequency modulated continuous wave (FMCW) radar.
Operating initially in the frequency range of 19.00-20.15 GHz, the mmWave PLL is engineered to extend to radar frequency bands from 38-40.5 GHz and even further to 76-81 GHz through frequency multipliers. Its scalable frequency configuration makes it suitable for diverse applications including 5G networks and various mmWave communication devices, providing flexibility for adaptation to specific needs.
Key features include integrated bandgap references, low-dropout regulators (LDOs), and integrated frequency multipliers. The PLL supports fractionally precise chirp modulation capabilities, making it ideal for automotive radar applications like collision avoidance and distance measurement. The device is robust, maintaining optimal performance across a wide temperature range, and includes comprehensive built-in self-test and calibration features to facilitate reliable deployment in high-demand environments.
