  • Sampling PLL for high resolution radar systems
    Patent number: 6385266
    Abstract: A low-noise sampling PLL for high-resolution radar systems wherein the reference frequencies are taken from a line spectrum (SPK), which has been generated from the mixture of a low quartz oscillator frequency (F1) with a high quartz oscillator frequency (F2), with the quartz oscillator frequencies (F1, F2) being synchronized. The invention is employed in connection with sampling PLLs for high-resolution radar systems with a controllable frequency oscillator, whose output signal is partially coupled out into a feedback branch and compared with reference frequencies in a phase comparator.
