New: low-jitter microwave clock source
Microsource is introducing a low-jitter microwave clock source aimed at converter-heavy radar, EW, SATCOM, and phased-array architectures where timing quality directly affects signal fidelity.
- 10.24 GHz nominal output
- 2-6 fs RMS jitter class
- Designed for radar, EW, SATCOM, and beamforming paths
- Built for real subsystem integration, not just bench evaluation
System Context
How Microsource fits into the RF signal chain
Microsource products are usually chosen as part of a larger architecture, not as stand-alone boxes. This simplified view shows how source generation, spectral control, frequency translation, and subsystem packaging work together in practical RF and microwave programs.
1
Generation and extension
Start with the source plan. YIGs, DROs, synthesizers, and non-linear multipliers establish or extend the signal where phase noise, tuning range, and frequency coverage matter first.
Typical products
YIG oscillators, DROs, synthesizers, multipliers
2
Filtering and translation
Once the source is set, filtering and linear conversion shape the spectrum and move the signal into the band the architecture actually needs without losing sight of the full IF and LO plan.
Typical products
YIG filters, linear up-converters, linear down-converters
3
Output and integration
The final stage is making the chain usable in the real platform. Amplification, interfaces, mechanical packaging, and custom integrated assemblies turn the design into deployable hardware.
Typical products
Amplifiers, integrated microwave assemblies, custom engineering

Mission environments
Built for the systems where RF performance has consequences
Microsource hardware is used in environments where timing, spectral purity, and subsystem integration are tied directly to mission performance rather than bench-top convenience.
Radar and fire control
Coherent source, translation, and filtering paths for tracking, surveillance, and precision radar architectures.
Electronic warfare
Wideband microwave generation, conversion, and control paths for contested-spectrum sensing and response systems.
SATCOM and airborne links
Stable sources and integrated RF hardware for communications payloads, airborne platforms, and precision link architectures.
Airborne and mobile platforms
Packaging and environmental discipline suited to deployed systems where SWaP, ruggedness, and repeatability all matter.
Why Microsource
Engineering depth, production discipline, and custom integration
The standard catalog brings technical teams in, but the long-term value is helping programs move from product selection to a buildable, supportable RF subsystem.
- Standard RF building blocks that speed early evaluation
- Custom subsystem work when packaging or performance breaks the catalog mold
- A path from engineering review through repeatable production support
