enabling next ~ Mixed-Signal Devices, a leading provider of multi-gigahertz timing solutions, has announced the release of their latest product, the MS4022 Frequency Synthesizer. This new device sets a new standard for RF performance with its impressive output frequencies of up to 22 GHz and ultra-low jitter of only 25 fs RMS. The MS4022 is specifically designed to meet the demanding requirements of next-generation radar, wireless infrastructure, phased array, and instrumentation systems.

The company will be showcasing the MS4022 at the International Microwave Symposium (IMS) 2025 in San Francisco from June 15-20. As RF, defense, and emerging 6G systems continue to push for higher data rates and tighter timing precision, engineers are facing increasing challenges related to noise, system complexity, and scalability. The MS4022 aims to address these challenges with its ultra-low phase noise, wideband frequency synthesis capabilities, and programmable versatility all within a compact form factor.

One of the key features of the MS4022 is its ability to seamlessly lock onto external reference sources such as OCXOs, GPS-disciplined oscillators (GPSDOs), and master clock trees. This allows for precise synchronization with system-level timing requirements. Additionally, it offers dual coherent outputs for phase-aligned signal generation which is ideal for applications like beamforming, MIMO, and multi-channel instrumentation. The integrated jitter attenuation further enhances performance by suppressing reference noise and ensuring exceptionally low phase noise levels. These features make it suitable for integration into both stand-alone and distributed architectures where deterministic and high-integrity timing is crucial.

Avi Madisetti, CEO of Mixed-Signal Devices stated that "With RF systems moving towards higher frequencies, traditional analog PLL-based synthesizers are unable to keep up." He further explained that "The MS4022 utilizes digital synthesis technology to provide next-generation performance which enables cleaner signals, tighter phase alignment, and reduced design complexity across critical RF applications."

More on The Californer
The MS4022 Frequency Synthesizer boasts a range of impressive features including a frequency range of 675 MHz to 22 GHz with dual phase-coherent outputs, ultra-low jitter of 25 fs RMS (12 kHz to 20 MHz), and flexible reference options supporting internal and external clocking from 1 PPS up to 750 MHz. It also offers interface options such as USB-C for user programmability and optional SPI. The device is suitable for a wide range of applications including FMCW, doppler, and SAR radar, phased array and MIMO RF front-ends, 5G/6G transceiver development, test and measurement systems requiring wideband LO sources, and low-noise clock generation for high-speed converters.

The MS4022 simplifies the development of modern RF systems with its integrated control for output frequency, sweep mode, power level, and step size. This allows for precise signal generation over a wide bandwidth with minimal phase noise distortion.

The MS4022 is currently available for sampling and will be featured at the Mixed-Signal Devices booth (361) at the IEEE MTT-S International Microwave Symposium (IMS) in San Francisco.
