September 17, 2012. Noise eXtended Technologies (Noise XT) announced at Autotestcon 2012 the LNS-18, a new general-purpose low-noise synthesizer. The LNS-18 is suitable for driving up- and down-converters for defense and space applications where phase noise is critical.
“Current synthesizers' best specifications in the X band are in the vicinity of 125 dBc/Hz at 10-kHz offset. Noise XT's LNS-18 breaks the -130dBc/Hz barrier with our lower cost solution,” said Guillaume de Giovanni, president, Noise XT. “Phase noise often limits radar performance and satellite transmission bit error rate. Having a low noise source in the lab can greatly help when designing and testing innovative products.”
The LNS-18 is a general-purpose synthesizer. Its low-noise oscillators generate a flexible frequency range up to 18 GHz. With -132 dBc/Hz at a 10-GHz carrier and 20-kHz offset, the LNS-18 is designed to test the most advanced components and systems for demanding applications in military and aerospace applications. Optional level control, pulse modulation, GPIB, and low frequency extension down to 8 MHz using ultra-low noise frequency dividers (-165 dBc/Hz) are available in addition to Ethernet and EFC input.
The LNS-18 has an output frequency of 4 to 18 GHz (with option for 8 MHz minimum), an output level of +13 dBm (±2 dB), and non-harmonic spurious of < -50 dBc from 1 Hz to 1 kHz offset and < -80 dBc above 1 kHz offset.
