Product Description
Spinnaker Microwave SMS-DA-CR146186 Fast Tuning Frequency Synthesizer
This is a Spinnaker Microwave SMS-DA-CR146186, a fast-tuning frequency synthesizer designed for high-speed frequency hopping in demanding RF applications such as electronic warfare (EW), radar, secure communications, and advanced test systems. Engineered for low phase noise and rapid switching, this module is sold AS IS for engineering evaluation, parts salvage, or integration into specialized RF architectures.
Key Specifications (Based on Spinnaker’s Product Line):
-

Potential Uses:
-
Military RF System Repair: Donor synthesizer for restoring an identical Spinnaker-based radar, EW, or comms system.
-
Component Salvage: High-value VCOs, PLL chips, RF amplifiers, isolators, filters, and precision regulators.
-
Advanced RF Research: For university or corporate R&D in frequency-hopping, cognitive radio, or radar prototyping.
-
Test System Enhancement: Upgrade a lab signal generator or custom test bed with fast-switching capability.
Important Notes:
-
Control Protocol Unknown: Operating this synthesizer requires knowledge of its control interface and programming sequence, which is not provided.
-
Power & Signal Integrity: Requires a low-noise, well-regulated power supply and proper RF shielding for optimal performance.
-
ITAR/EAR Controlled: Likely subject to U.S. export regulations due to its military-grade fast-tuning capabilities.
-
Expertise Required: Suitable only for RF engineers with experience in frequency synthesizers, phase-locked loops, and microwave test equipment.
