Raytheon CUM21 RF circulator

Product Description

Raytheon CUM21 RF/Microwave Circulator

This is a Raytheon CUM21, a military-grade RF circulator designed for non-reciprocal signal routing in radar, communication, and electronic warfare systems. Circulators are critical for isolating transmitters from receivers, managing signal flow, and protecting sensitive components. Sold AS IS for technical evaluation, parts salvage, or repair of legacy RF systems.

Key Features (Typical of Circulators):

• Type: 3-port or 4-port ferrite circulator (non-reciprocal)

• Frequency Range: Likely in the S-band, C-band, or X-band (common for military applications)

• Power Handling: Medium to high power (typical for radar systems)

• Connectors: SMA, N-Type, or TNC (common for military RF)

• Construction: Ruggedized, hermetically sealed (typical for Raytheon military components)

• Applications: Radar duplexing, transmitter/receiver isolation, signal routing in EW/ECM systems

Potential Uses:

• Component Salvage: High-quality ferrite core, magnets, connectors, and housing

• Legacy System Repair: Donor part for restoring an identical functioning circulator in military or aerospace hardware

• RF Experimentation: For advanced hobbyists or engineers studying non-reciprocal components (requires network analyzer for characterization)

• Educational Display: Example of military RF component design for engineering programs

Important Notes:

• Expertise Required: This component is not functional without integration into a properly matched RF system.

• No Performance Guarantee: Assume non-working until tested with a vector network analyzer (VNA) under correct bias and frequency conditions.

• Military Heritage: Likely subject to ITAR/EAR regulations; international sales may be restricted.
