Frequency synthesizer boasts low phase noise
Test & Measurement World Staff - September 11, 2012
Noise eXtended Technologies (Noise XT) announced the LNS-18, a general-purpose low-noise synthesizer that can be used as a signal source for driving up-converters and down-converters in defense and aerospace applications where phase noise is critical. “Current synthesizers’ best specifications in the X band are in the vicinity of –125 dBc/Hz at a 10-kHz offset. Noise XT’s LNS-18 breaks the –130-dBc/Hz barrier,” said Guillaume de Giovanni, president of 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.”
Covering a frequency range of 4 GHz to 18 GHz, the LNS-18 provides phase noise of –132 dBc/Hz at a 10-GHz carrier and 20-kHz offset. Output level is +13 dBm (±2 dB), while nonharmonic spurious is less than –50 dBc from a 1-Hz to 1-kHz offset and less than –80 dBc above a 1-kHz offset. Optional features include level control, pulse modulation, GPIB interface, and low-frequency extension down to 8 MHz using ultra-low-noise frequency dividers (–165 dBc/Hz). An Ethernet port and EFC (electrical frequency control) input are also available.
