This article reports on a millimeter-wave (MM-wave) signal down-conversion system with low phase noise for chip-scaled optical clocks. The system utilizes analog regenerative frequency division, low-noise fractional frequency division, and phase-locked frequency division techniques to down-convert a 100 GHz MM-wave signal to 100 MHz with phase noise of -117 dBc/Hz @100 Hz, -133 dBc/Hz @1 kHz, and 10 MHz with phase noise of -124 dBc/Hz @100 Hz and -143 dBc/Hz @1 kHz. The frequency stability of the signal down-converted to 100 MHz is 5.

Article Synopsis
  • Syndromic hearing loss (SHL) involves diverse genetic causes, with over 400 types identified, primarily following an autosomal dominant inheritance pattern.
  • A study analyzed 14 patients (ages 5-78 months) with various syndromes associated with SHL, discovering ten new genetic variants and confirming cases of well-known syndromes like Waardenburg and CHARGE.
  • Results suggest that combining neonatal hearing screenings with whole exome sequencing can effectively diagnose SHL early, highlighting the need for thorough monitoring of patients due to the complexity and variability of SHL symptoms.
