MLVS-0520 ~ Micro Lambda Luxyn Synthesiser
This fast-switching frequency synthesizer keeps the spurious and phase-noise levels low across a total frequency tuning range as wide as 50 MHz to 21 GHz.
Microwave signal sources must deliver on many different levels. Depending on the application, they may need to switch frequencies quickly, often in fine frequency steps, and always with low phase noise. Achieving this combination of high performance levels in a small package adds to the design challenge, but such challenges bring out the best in an experienced microwave source designer such as Micro Lambda’s Alexander Chenakin, who unveiled his latest creation at the recent 2017 IEEE International Microwave Symposium (IMS) exhibition in Honolulu.

The Luxyn frequency synthesizer features high-speed tuning from 50 MHz to 21 GHz in frequency steps as small as 0.001 Hz in a package that is only 4.0 × 3.6 × 0.9 in. and weighs only 15 oz. It is literally a fit for a wide range of applications, from broadband communications systems to test-and-measurement equipment. It provides spectrally pure output signals that can feed most measurement applications.
The Luxyn frequency synthesizers are based on a stabilized voltage-controlled oscillator (VCO) with extremely wide tuning range and fast frequency switching speed. The tuning range of a standard Luxyn model MLVS-0520 frequency synthesizer is 500 MHz to 20 GHz, with lower frequencies available to 50 MHz and higher frequencies available to 21 GHz. Of course, Micro Lambda is well known for its YIG-oscillator-based frequency synthesizers and the two microwave source technologies have traditionally represented two sets of tradeoffs for high-frequency signal sources. YIG oscillators and synthesizers have long been standards of sorts for low phase noise, although for the penalty of limited tuning speed. Frequency synthesizers such as phase-locked-loop (PLL) sources based on VCOs have been traditionally capable of extremely fast tuning speeds but with limited phase-noise performance compared to YIG-based synthesizers. The Luxyn series of synthesizers combines the best of both source technologies, with fast switching speed and low phase noise—in general, with low noise levels. It also achieves the small size and weight made possible by building the synthesizer circuitry around a miniature VCO.
