Frequency Synthesizers Come On Strong at IMS

Frequency synthesizers provide the stable high-frequency signals for transmit and receive functions in many systems, and advances continue to be made in this technology. As evidence, Micro Lambda Wireless (booth No. 1101) introduced the Luxyn™ frequency synthesizer at the 2017 IMS exhibition, a source developed by renowned synthesizer designer Alexander Chenakin. It combines low phase noise and fast switching speed in a compact housing.

Housed in a coaxial module measuring just 4.0 x 3.6 x 0.9 in., the compact frequency synthesizer tunes from 50 MHz to 21 GHz in steps as small as 1 mHz and features 50-us switching speed. Minimum output power is +15 dBm across the frequency range. Perhaps even more impressive is the phase noise, at only -130 dBc/Hz offset 10 kHz from a 5-GHz carrier and only -125 dBc/Hz offset 10 kHz from a 10-GHz carrier.  Harmonics are typically -12 dBc and spurious content is typically -60 dBc. For more details on this ground-breaking frequency synthesizer, don’t miss the full-length Product Feature in the July issue of MicroWaves & RF.
