IRVINE, Calif., June 16, 2025 —IMS 2025 — Mixed-Signal Devices, a leader in multi-gigahertz timing solutions, today announced the MS4022 Frequency Synthesizer, setting a new benchmark in RF performance. With output frequencies up to 21.6 GHz and ultra-low jitter of just 25 fs RMS, the MS4022 is designed to meet the stringent demands of next-generation radar, wireless infrastructure, phased array, and instrumentation systems. The MS4022 will be demonstrated at the International Microwave Symposium (IMS) 2025, taking place June 15–20 in San Francisco.

As RF, defense, and emerging 6G systems push for higher data rates, tighter timing precision, and greater spectral efficiency, engineers face mounting challenges related to noise, system complexity, and scalability. The MS4022 meets these demands with ultra-low phase noise, wideband frequency synthesis, and programmable versatility in a compact form factor. 

The MS4022 supports seamless locking to external reference sources—including OCXOs, GPS-disciplined oscillators (GPSDOs), and master clock trees—enabling precise synchronization with system-level timing requirements. It provides dual coherent outputs for phase-aligned signal generation, well-suited for applications such as beamforming, MIMO, and multi-channel instrumentation. Integrated jitter attenuation further enhances performance by suppressing reference noise, ensuring exceptionally low phase noise. These capabilities support reliable integration into both stand-alone and distributed architectures where deterministic and high-integrity timing is critical.

“With RF systems moving to higher frequencies, legacy analog PLL-based synthesizers can’t keep up,” said Avi Madisetti, CEO of Mixed-Signal Devices. “The MS4022 utilizes digital synthesis to provide next-generation performance, enabling cleaner signals, tighter phase alignment, and reduced design complexity across critical RF applications.”

Mixed-Signal Devices MS4022 Frequency Synthesizer Key Features:

• Frequency Range: 675 MHz to 22 GHz with dual phase-coherent outputs
• Ultra-Low Jitter: 25 fs RMS (12 kHz to 20 MHz)
• Reference Flexibility: Supports internal and external reference clocking from 1 PPS up to 750 MHz
• Interface Options: USB-C for user programmability, SPI optional
• Applications: 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.

With integrated control for output frequency, sweep mode, power level, and step size, the MS4022 simplifies development of modern RF systems requiring precise, wideband signal generation and minimal phase noise distortion.
