OCXOs deliver ultra-low noise

Q-Tech Corp. has announced the availability of the AXIOM line of ultra-low noise (ULN) OCXOs from its German affiliate, Axtal.  The new line is available in custom versions, offering designers specific frequencies and modules with multiple outputs.

The new AXIOM OCXOs with ultra-low close-in phase noise and noise floor enable higher resolution for radar systems, higher quality and more transmissible information in communications systems and higher accuracy and lower measurement limits in RF measurement systems, said the company.

The new devices include the AXIOM145ULN for communications systems and RF measurement systems that typically require 10-MHz OCXOs. It features frequency over temperature stability of 5 to 20 ppb; close-in phase noise of <-115 dBc/Hz @ 1 Hz offset and a noise floor of <-170 dBc/Hz @ ≥100kHz. Radar and other similar applications require frequency generation from MHz to GHz, Q-Tech said.

Also available are the AXIOM75ULN and AXIOM5050ULN (80 to 160 MHz) and multiple-output AXIOM2700 (50 MHz to 7.0 GHz) that are well suited for these applications. They offer close-in phase noise of <-140 dBc/Hz @ 100 Hz offset, and noise floors down to -185 dBc/Hz, respectively (at 100 MHz carrier frequency).

“AXTAL not only offers ULN OCXOs operating over broad frequency ranges, but entire custom modules, which generate GHz signals using frequency multiplication and/or phase-locked loop (PLL) techniques,” said Henry Halang, AXTAL’s managing director, in a statement. “These modules are fully customizable providing customers with maximum design flexibility.”
