Q-Tech Corporation announced the availability of the AXIOM line of ultra-low noise (ULN) oven-controlled crystal oscillators (OXCOs). Designed and manufactured by Q-Tech’s German affiliate, AXTAL, the benefits of the AXIOM OCXOs ultra-low phase noise (close-in and noise floor) are higher resolution for radar systems, better quality and more transmissible information for communications systems and improved accuracy and lower measurement limits for RF measurement systems. Ultra-low phase noise OCXOs can be customized to achieve near-ideal multiplication and, by allowing the use of various noise-cancellation techniques, they can transfer noise levels up to the GHz range. They also reduce jitter — an important consideration in these applications — with RMS jitter values of < 50 fs for integration ranges of 10 Hz ~ 30 MHz.
The AXTAL line of ultra-low phase noise AXIOM OCXOs comprises 16 devices, including the AXIOM75ULN and AXIOM5050ULN (80 to 160 MHz) and the multiple-output AXIOM2700 (50 MHz to 7.0 GHz), all offering exceptional phase noise. At lower frequencies (non-multiplied), the AXIOM ULN OCXOs can obtain levels of <-140 dBc/Hz at 100 Hz offset and a noise floor down to -185 dBc/Hz. These benefits make ultra-low phase noise AXIOM OCXOs ideal for use in a range of sophisticated applications requiring frequency generation from MHz to GHz.
“AXTAL’s ‘ULN’ devices provide a selection of OCXOs operating over broad frequency ranges with the option of creating fully customizable modules using frequency multiplication and/or PLL techniques,” said Henry Halang, AXTAL’s managing director. “With the ability to generate signals at GHz levels, ULN OCXOs offer our customers maximum design flexibility and superior performance.”
